[dev.ssa] cmd/compile/internal/ssa: implement write barriers

For now, we only use typedmemmove.  This can be optimized
in future CLs.

Also add a feature to help with binary searching bad compilations.
Together with GOSSAPKG, GOSSAHASH specifies the last few binary digits
of the hash of function names that should be compiled.  So
GOSSAHASH=0110 means compile only those functions whose last 4 bits
of hash are 0110.  By adding digits to the front we can binary search
for the function whose SSA-generated code is causing a test to fail.

Binary Distribution Notes

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

See https://golang.org/doc/install or doc/install.html for more details.
