Revert "liblzma: CLMUL CRC64: Workaround a bug in MSVC (VS2015-2022)."

This reverts commit 36edc65ab4cf10a131f239acbd423b4510ba52d5.

It was reported that it wasn't a good enough fix and MSVC
still produced (different kind of) bad code when building
for 32-bit x86 if optimizations are enabled.

Thanks to Iouri Kharon.
