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.
