[clang] Rename files that MacOS libtool warns about (NFC)users/jthackray/rename-files

As mentioned in https://discourse.llvm.org/t/rfc-rename-source-files-in-clang-lib-codegen-targetbuiltins/87462/
it appears that MacOS's libtool warns about source filenames that
are identically named, even if they exist in separate directories.

Sadly, there doesn't appear to be an easy way to disable this warning,
so rename these files, as these warnings are annoying for MacOS users.

Fixes #133199.
