We now print ST0 as 'st' when generating the clobber list for MS inline assembly in clang. This matches what the gcc reg name list expects. Original commit message: This fixes the test case in PR35982 by preventing MMX instructions that read MM0-7 from being moved below EMMS/FEMMS by the post RA scheduler. Though as discussed in bugzilla, this is not a complete fix. There is still the possibility of reordering in IR or by the pre-RA scheduler.
