cmd/internal/gc: replace hash tables with Go maps

The C version of the compiler had just one hash table,
indexed by a (name string, pkg *Pkg) pair.
Because we always know the pkg during a lookup,
replace the one table with a per-Pkg map[string]*Sym.
This also lets us do non-allocating []byte key lookups.

This CL *does* change the generated object files.
In the old code, export data and init calls were emitted
in "hash table order". Now they are emitted in the order
in which they were added to the table.

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.
