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.

87155d4f6c cmd/go: ignore errors from go/build for standard packages
The go/build package does not know that gccgo's standard packages don't
    have source, and will report an error saying that it can not find them.
    Work around that in the cmd/go sources, since the go/build sources don't
    currently have a list of standard packages.
    
    This should get a real fix in the master sources, somehow.
    
    Fixes golang/go#16701.

PR go/66904
    cmd/go: fix "#cgo pkg-config:" comments with gccgo
    
    Copy of https://golang.org/cl/18790 by Michael Hudson-Doyle.
    
    The unique difficulty of #cgo pkg-config is that the linker flags are recorded
    when the package is compiled but (obviously) must be used when the package is
    linked into an executable -- so the flags need to be stored on disk somewhere.
    As it happens cgo already writes out a _cgo_flags file: nothing uses it
    currently, but this change adds it to the lib$pkg.a file when compiling a
    package, reads it out when linking (and passes a version of the .a file with
    _cgo_flags stripped out of it to the linker). It's all fairly ugly but it works
    and I can't really think of any way of reducing the essential level of
    ugliness.
    
    Update golang/go#11739.

dcfa3345eb cmd: Use correct install tool dir with gccgo
When using the go command built from gccgo to build and
    install a go tool, use the value from runtime GCCGOTOOLDIR as
    the install directory.
    
    This also fixes the output from 'go tool' when used with the
    gccgo-built go command, to only include the go tools and not
    other binaries found in the same directory.

    This is a backport of https://golang.org/cl/16775.
    
    This is, in effect, what the gc toolchain does.  It fixes cases where Go
    code refers to a C global variable; without this, if the global variable
    was the only thing visible in the C code, the generated cgo file might
    not get pulled in from the archive, leaving the Go variable
    uninitialized.

9f5059b275 go/cmd/go: always link external test packages first
When linking complex packages that use both internal and external tests as well as many dependencies it is critical that the link order be external test package, internal test package, everything else.

This change is a back (forward?) port of the same change that canonical have been maintaining on their fork of the go tool for gccgo. Now that gccgo uses the go tool from upstream, this patch should be applied both to the gofrontend and golang/go repos.

cmd: Fix dependencies for 'go get' with gccgo

Problem described in GCC BZ 65462.
Generate the list of the standard GO package names based on what was built into libgo in the libgo Makefile.
Change the var name from reqPkgSrc to reqStdPkgSrc to clarify it only affects standard GO packages.
Skip the attempted loading of a package only if it is a standard GO package and the flag is set indicating its source is not required to be available.
This requires a corresponding change to gotools to build and link in the new file containing the list of standard GO package names that was generated by the libgo Makefile.

f8d9fa9e80 libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.
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.
