All patterns that insert mode switching code via LCM should be marked as
clobbering the flags. fix_trunc* patterns were fixed by PR12308, but
floordf, floorsf, floorxf, ceildf, ceilsf, ceilxf, btruncdf, btruncsf, btruncxf,
nearbyintdf, nearbyintsf and nearbyintxf should still be fixed.
Actually, all patterns that set ix86_optimize_mode_switching = 1 needs to be
marked as clobbering the flags.
