This is a patch that disables the poison-unsafe select -> and/or i1 folding. It has been blocking D72396 and also has been the source of a few miscompilations described in llvm.org/pr49688 . D99674 conditionally blocked this folding and successfully fixed the latter one. The former one was still blocked, and this patch addresses it. Note that a few test functions that has `_logical` suffix are now deoptimized. These are created by @nikic to check the impact of disabling this optimization by copying existing original functions and replacing and/or with select. I can see that most of these are poison-unsafe; they can be revived by introducing freeze instruction. I left comments at fcmp + select optimizations (or-fcmp.ll, and-fcmp.ll) because I think they are good targets for freeze fix.
