Along with the update this fixes a problem that was always present but
only showed up with the new reflect test. When a program used a
**unsafe.Pointer and stored the value in an interface type, the
generated type descriptor pointed to the GC data for *unsafe.Pointer.
It did that by name, but we were not generating a variable with the
right name.

Compiler changes:
* Change map assignment to use mapassign and assign value directly.
* Change string iteration to use decoderune, faster for ASCII strings.
* Change makeslice to take int, and use makeslice64 for larger values.
* Add new noverflow field to hmap struct used for maps.
Unresolved problems, to be fixed later:
* Commented out test in go/types/sizes_test.go that doesn't compile.
* Commented out reflect.TestStructOf test for padding after zero-sized field.

Update a few binary files that were changed in the master gc repo,
copied into the gofrontend repo, but not correctly copied into the GCC
repo. The changes are all minor and do not affect any actual tests.
Two instances of "http" changed to "https", and two timestamps were
zeroed out.

reflect, encoding/json, encoding/xml: fix unexported embedded structs
Bring in three changes from the master Go repository. These changes
will be in Go 1.6, but they are appropriate for gccgo now because they
resolve a long-standing discrepancy between how gc and gccgo handle the
PkgPath field for embedded unexported struct fields. The core issue is
described at https://golang.org/cl/7247. This has been reported against
gccgo as https://gcc.gnu.org/PR66138.
The three changes being brought over are:

reflect: adjust access to unexported embedded structs
This CL changes reflect to allow access to exported fields and
methods in unexported embedded structs for gccgo and after gc
has been adjusted to disallow access to embedded unexported structs.
Adresses #12367, #7363, #11007, and #7247.

This upgrades all of libgo other than the runtime package to
the Go 1.4 release. In Go 1.4 much of the runtime was
rewritten into Go. Merging that code will take more time and
will not change the API, so I'm putting it off for now.
There are a few runtime changes anyhow, to accomodate other
packages that rely on minor modifications to the runtime
support.
The compiler changes slightly to add a one-bit flag to each
type descriptor kind that is stored directly in an interface,
which for gccgo is currently only pointer types. Another
one-bit flag (gcprog) is reserved because it is used by the gc
compiler, but gccgo does not currently use it.
There is another error check in the compiler since I ran
across it during testing.

* Makefile.am (go_cmd_go_files): Sort entries. Add generate.go.

This revision was committed January 7, 2014. The next
revision deleted runtime/mfinal.c. That will be done in a
subsequent merge.
This merge changes type descriptors to add a zero field,
pointing to a zero value for that type. This is implemented
as a common variable.
* go-gcc.cc (Gcc_backend::implicit_variable): Add is_common and
alignment parameters. Permit init parameter to be NULL.
