  Log Message:
  -----------
  [Clang] Produce deterministic hash for anonymous namespaces. (#194542)

This change adds a path substitution for the main module file during
anonymous namespace hash generation using the prefix map specified by
-fmacro-prefix-map option. That ensures deterministic symbol mangling
for reproducible builds.
