(move_or_delete_vzeroupper): Process and rescan all all basic
blocks instead of predecessor blocks of all exit points.
(ix86_option_override_internal): Enable vzeroupper optimization
only for -fexpensive-optimizations and not optimizing for size.
(use_avx256_p): Removed.
(init_cumulative_args): Don't set use_avx256_p.
