Normalized module cache path is `X` from `-fmodules-cache-path=X` that was made
absolute, and with `llvm::sys::path::remove_dots()` applied. I believe this is
done mainly so that the `IMPORT` statements in PCM files contain absolute
paths, making it possible to load transitively PCMs regardless of the importer
CWD.
Specific module cache path is the normalized module cache path with the context
hash appended as a subdirectory (unless suppressed by `-fdisable-module-hash`).
This is (somewhat poorly) documented in the `HeaderSearch` member.
