[llvm] Revert "[llvm] Fix assertion error where we didn't check fixed point types." (PR #82285)

[Vladimir Vereschaka via llvm-commits]

https://github.com/vvereschaka created https://github.com/llvm/llvm-project/pull/82285

These changes break the `LLVM::fixed-point.ll` test some targets what fails the builds for those targets
(more details https://github.com/llvm/llvm-project/pull/80757#issuecomment-1949382211)

The problem wasn't fixed for few days,
