[PATCH] D87888: [X86] Use inlineasm flag output for the _bittest* intrinsics.

rnk added a comment.

Honestly, I forget exactly what the memory clobber does beyond the "sideeffect" marker. I would expect LLVM to model these just as external function calls that could read or write memory that is passed to them.
