[PATCH] D80681: [clang][SourceManager] cache Macro Expansions

[Nick Desaulniers via Phabricator via cfe-commits]

I've forked off

1. D82497 <https://reviews.llvm.org/D82497> (`getFileIDLocal` optimizations)
2. D82498 <https://reviews.llvm.org/D82498> (don't check `Invalid` for calls to `getLocalSLocEntry`)

I agree those should be the less controversial parts of this diff.  Once those are landed, I'll rebase this change to just contain the caching logic change.
