[PATCH] D57642: [X86] Update clobber list in a test after D57641. Remove filter for 'fpsw' in MS inline asm clobber list generation since the backend now uses 'fpsr'.

The backend used to print the x87 FPSW register as 'fpsw', but gcc inline asm uses 'fpsr'. After D57641 <https://reviews.llvm.org/D57641>, the backend now uses 'fpsr' to match. So we need to update the test and we can remove the code that excluded the 'fpsw' string.
