Reapply after https://github.com/llvm/llvm-project/pull/93548, which should address the lldb failure on macos. ----- Do not create icmp/fcmp constant expressions in IRBuilder etc anymore, i.e. treat them as "undesirable". This is in preparation for removing them entirely. Part of: https://discourse.llvm.org/t/rfc-remove-most-constant-expressions/63179
