compiler: insert additional conversion for type desc ptr expr
Change the method Type::type_descriptor_pointer to apply an additional
type conversion to its result Bexpression, to avoid type clashes in
the back end. The backend expression for a given type descriptor var
is given a type of "_type", however the virtual calls that create the
variable use types derived from _type, hence the need to force a
conversion.

compiler: insure tree integrity in Call_expression::set_result
Depending on the back end, it can be problematic to reuse Bexpressions
(passing the same Bexpression to more than one Backend call to create
additional Bexpressions or Bstatements). The Call_expression::set_result
method was reusing its Bexpression input in more than one tree
context; the fix is to pass in an Expression instead and generate
multiple Bexpression references to it within the method.

compiler: don't crash if imported package imports this one
When building a test it's OK if test code imports a package that

creates an impossible initialization order. The compiler already has
code to permit this in Gogo::add_import_init_fn. This CL avoids a
compiler crash on a similar case when writing out the export data.
I have no test case for this. Basically it pushes a compiler crash
into an error reported elsewhere.

compiler, runtime: don't let slices point past end of memory block
When Go code uses a slice expression like [:len(str)] or [:cap(slice)],
it's natural for the resulting pointer to point just past the end of
the memory block. If the next memory block is not live, we now have a
live pointer to a dead block, which will unnecessarily keep the block
alive. That wastes space, and with the new Go 1.8 GC (not yet
committed) will trigger an error when using GODEBUG=gccheckmark=1.
This changes the implementation of slice expressions to not move the
pointer if the resulting string length or slice capacity is 0. When
the length/capacity is zero, the pointer is never used anyhow.

This changes the gofrontend code to emit write barriers as needed.
This is in preparation for future changes. At the moment the write
barriers will do nothing. They test runtime.writeBarrier.enabled,
which will never be non-zero. They call simple functions which just
do a move without doing any of the other operations required by the
write barrier.

compiler: add code to generate a ptrmask for a type
The Go 1.8 garbage collector uses a ptrmask for all types below a
certain size. A ptrmask is simply a bit vector with a single bit for
each pointer-sized word in the value. The bit is 1 if the type has a
pointer in that position, 0 if it does not.
This change adds code to the compiler to generate a ptrmask. The code
is not used by anything yet, it is just compiled. It will be used

compiler: add code to generate a gcprog for a type
The Go 1.8 garbage collector uses a gcprog for all types above a
certain size. A gcprog describes where the pointers are in the type,
using a simple bytecode machine that supports repeating bits. The
effect is to permit using much less space to describe arrays. The
format is described in runtime/mbitmap.go in the docs for runGCProg.
This is not yet added to the gofrontend, but can be seen in the gc sources.
This change adds code to the compiler to generate a gcprog. The code
is not used by anything yet, it is just compiled. It will be used
when we switch over to the Go 1.8 garbage collector.

compiler: add ptrdata computations and expressions
For the upcoming Go 1.8 GC we need to compute the "ptrdata" of a type:
the number of bytes in the type that can contain pointers. For types
that do not contain pointers this number is zero. For many types it
is a number larger than zero but smaller than the total size of the
type. The Go 1.8 GC uses this number to make loops looking for
pointers run faster by not scanning the suffix of a value that can not
contain a pointer.
Unfortunately there are two subtly different definitions of ptrdata,
and we need both. The first is the simple one: the prefix that can
contain pointers. The second is the number of bytes described by the
gcprog for the type. Recall that we describe the exact position of
pointers in a type using either a ptrmask or a gcprog. The ptrmask is
simpler, the gcprog uses less space. We use the gcprog for large
types, currently defined as types that are more than 2048 bytes. When
the Go 1.8 runtime expands a gcprog, it verifies that the gcprog
describes exactly the same number of bytes as the ptrdata field in the
type descriptor. If the last pointer-containing portion of a type is
an array, and if the elements of the array have a ptrdata that is less
than the size of the element type, then the simple definition of the
ptrdata will not include the final non-pointer-containing bytes of the
last element of the array. However, the gcprog will define the array
using a repeat count, and will therefore include the full size of the
last element of the array. So for a type that needs a gcprog, the
ptrdata field in the type descriptor must be the size of the data
described by the gcprog, and that is not necessarily the same as the
simple ptrdata.
It might seem that we can always use the gcprog version of the ptrdata
calculation, since that is what will appear in a type descriptor, but
it turns out that for global variables we always use a ptrmask, not a
gcprog, even if the global variable is large. This is because gcprogs
are handled by expanding them into a ptrmask at runtime, and for a
global variable there is no natural place to put the ptrmask. Simpler
to always use the ptrmask. That means that we need to describe the
size of the ptrmask, and that means that we need an expression for the
simple form of the ptrdata.
This CL implements the ptrdata calculation. This code is not actually
used yet. It will be used later when the Go 1.8 GC is committed.

compiler: don't write struct with multiple sink fields to C header file
When writing a struct to the C header file used by the C runtime code,
a single sink field is fine: it will be called "_", which is valid C.
There are structs with single sink fields that we want to write out,
such as finblock. As it happens, though, the Go 1.8 runtime has a
struct with two sink fields, gcControllerState, which will produce a C
definition with two fields named "_", which will fail. Since we don't
need to know that struct in C, rather than fix the general case, just
punt if the struct has multiple sink fields.
After the conversion to the Go 1.8 GC, we may be able to get rid of
the C header file anyhow. I'm not sure yet.

runtime: change g's in systemstack
The systemstack function in the gc toolchain changes to a different g.
This is often used to get more stack space; the gofrontend uses a
different stack growth mechanism that does not require changing g's,
so we've been running with a version of systemstack that keeps the
same g. However, the garbage collector has various tests to verify
that it is running on g0 rather than on a normal g. For simplicity,
change the gofrontend version of systemstack to change to a different
g just as the gc toolchain does.
This permits us to uncomment some sanity checks in notetsleep.
Doing that requires us to fix up a couple of places where C code calls
{start,stop}TheWorldWithSema while not on g0.
Note that this does slow down some code in the runtime package unnecessarily.
It may be useful to find some places where the runtime calls
systemstack only to get more stack space and change it to use some
other function. That other function would act like systemstack in the
gc toolchain but simply call the argument in the gofrontend.

For the current GC this means we have to explicitly scan the

runtime: copy garbage collector from Go 1.8 runtime
This giant patch replaces the old Go 1.4 memory allocator and garbage
collector with the new Go 1.8 code. The memory allocator is fairly
similar, though now written in Go rather than C. The garbage
collector is completely different. It now uses ptrmask and gcprog
information, which requires changes in the compiler and the reflect
package as well as the runtime. And, of course, the garbage collector
now runs concurrently with program execution.
In the gc toolchain the garbage collector is strict and precise at all
levels. In the gofrontend we do not have stack maps, so stacks, and
register values, are collected conservatively. That means that an
old, no longer used, pointer on a stack or in a register can cause a
memory object to live longer than it should. That in turns means that
we must disable some checks for invalid pointers in the garbage
collection code. Not only can we get an invalid pointer on the stack;
the concurrent nature of the collector means that we can in effect
resurrect a block that was already unmarked but that the collector had
not yet gotten around to freeing, and that block can in turn point to
other blocks that the collector had managed to already free. So we
must disable pointer checks in general. In effect we are relying on
the fact that the strict pointer checks in the gc toolchain ensure
that the garbage collector is correct, and we just assume that it is
correct for the gofrontend since we are using the same code.

libgo: delete goc2c
The last .goc file has been removed, so remove goc2c.
The goc2c program was my first contribution to the gc repository that
was more than 100 lines:
2b57a1124e
The program was used in gc for a few years under various guises but
was finally removed in https://golang.org/cl/132680043. Now we can
remove it from gofrontend as well.

compiler: set "need_init_fn" when adding gc root
Variables that back slice initializers in certain cases have to be
added to the gc roots list, since they can be modified at runtime. The
code that was doing this addition did not update the flag that tracks
whether the package being compiled needs an initializer function,
which resulted in the call in question being left out of the final
generated code in certain cases. Fix is to change Gogo::add_gc_root()
to update the "needs init" flag.

compiler: fix variable context nit in write barrier generation
Update the write barrier generation code to insure that the "lvalue
context" tag on the space var expression is set only in the case where
the expr feeds directly into an assignment. This is somewhat
counter-intuitive, but needed in the case where the backend looks at
context tags.
