Subject: PATCH: Set need frame pointer once

Hi,

Both compute_regsets in global.c and init_elim_table in reload1.c
check if frame pointer is needed.
frame_pointer_needed has to be consistent for stack alignment.
compute_regsets is called before
init_elim_table. This patch consolidates setting frame_pointer_needed
in compute_regsets. Tested
on
Linux/ia32, Linux/x86-64 and Linux/ia64.  OK for trunk?

Thanks
