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