This keeps the assert that checks that the llvm DataLayout and the user label prefix are in sync. See the NDEBUG in Mangle.cpp here-ish: https://reviews.llvm.org/D100776#change-NN4Lz7xH29fo (I measured that that assert doesn't slow down `check-clang` in a release+assert build too). So I don't think this regresses safety.
