Go compiler frontend (gccgo)

Latest commit 893f0e4 Feb 17, 2017 @ianlancetaylor ianlancetaylor libgo: update to final Go 1.8 release
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.

README

A Go frontend
=============

Last update 15 June 2014

This is a compiler frontend for the Go programming language
(http://golang.org/).  The frontend was originally developed at
Google, and was released in November 2009.  It was originally written
by Ian Lance Taylor <iant@golang.org>.

It was originally written for GCC (http://gcc.gnu.org/).  As of this
writing it only supports GCC, but the GCC support has been separated
from the rest of the frontend, so supporting another compiler is
feasible.

The go subdirectory holds the frontend source code.  This is mirrored
to the gcc/go subdirectory in the GCC repository.

The libgo subdirectory holds the library source code.  This is a copy
of the main Go library with various changes appropriate for this
compiler.  The main Go library is hosted at
http://go.googlesource.com/go, in the src directory.  The libgo
subdirectory is mirrored to the libgo subdirectory in the gcc
repository.
