Removing -frename-registers from -O3

[Bernd Schmidt]

Richard,

how do you feel about this patch?  IMO -frename-registers is too harmful
to debugging to include it by default on any target (except ia64 for
which it's uncommonly useful).

Maybe we ought to add some entries to TORTURE_OPTIONS, though.
