5g, 6g, 8g: registerize variables again

Browse source 
My previous CL:

changeset:   9645:ce2e5f44b310
user:        Russ Cox <rsc@golang.org>
date:        Tue Sep 06 10:24:21 2011 -0400
summary:     gc: unify stack frame layout

introduced a bug wherein no variables were
being registerized, making Go programs 2-3x
slower than they had been before.

This CL fixes that bug (along with some others
it was hiding) and adds a test that optimization
makes at least one test case faster.
