Duncan P. N. Exon Smith 608e4a390c Mark vastart_save_xmm_regs as changing EFLAGS ...

The vastart_save_xmm_regs pseudo-instruction expands to a test and a
branch, so it modifies EFLAGS.  Mark it so, or else the scheduler might
place it in the middle of another test+branch.

This fixes a bug exposed by r192750, which turned on the MI Scheduler
for X86.
