[Bug 92709] "LLVM triggered Diagnostic Handler: unsupported call to function ldexpf in main" when starting race in stuntrally

It seems bizarre that an llvm intrinsic would ever be changed to something involving a library call.

I think the exp2 -> ldexpf transform is rather questionable for us anyway, since we have a native exp2 instruction, isn't it? Maybe we just don't want to use the LibCallSimplifier pass? The comment at the top of SimplifyLibCalls.cpp kind of sounds like "this is not the pass you're looking for"...
