[X86] Fix expand-fp on optnone functions (#156900)
As observed by @mikaelholmen, PR #130988 "[AMDGPU] Implement IR expansion for frem instruction" introduced a regression on x86. Its changes led to the pass being skipped on functions with the optnone attribute. @bjope also noted that a check concerning the optnone handling is wrong. This patch fixes both issues which together fixes the regression. During the review it was observed that, even before PR #130988, the pass would not run on optnone functions with the new pass manager. This is also fixed.
