I moved just the hash part of this function to the llvm folder.
I suppose you're suggesting that the hash part needs to be moved to llvm to support implementing the `%lpad_label` asm operand modifier, which takes a mangled string and hash it into a 20-bit integer, so it's only the hashing part that needs to be re-located, not the whole mangling part.

Fixed.
