[dev.ssa] cmd/internal/gc: convert standard IR into SSA.
Hook into the current compiler to convert the existing
IR (after walk) into SSA. Any function ending in "_ssa"
will take this path. The resulting assembly is printed
and then discarded.
Use gc.Type directly in ssa instead of a wrapper for go types.
It makes the IR->SSA rewrite a lot simpler.
Only a few opcodes are implemented in this change. It is
enough to compile simple examples like
func f(p *int) int { return *p }
func g(a []int, i int) int { return a[i] }

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
