TargetLibraryInfo does not report exp10/exp10f/exp10l as available on Linux, disabling all special library call optimizations:
https://github.com/llvm/llvm-project/blob/c0682840877a21960f4c21a97b5f497d4ccc82d5/llvm/lib/Analysis/TargetLibraryInfo.cpp#L550
The reason cited is these were buggy in glibc prior to version 2.18. Version 2.18 celebrated its 10th birthday this weekend, so I think it's alright to just drop this restriction.
