[PATCH] D82690: [clang][SourceManager] cache Macro Expansions pt.2

[Nick Desaulniers via Phabricator via cfe-commits]

Alternatively, I could revert dffc1420451f674 <https://reviews.llvm.org/rGdffc1420451f674731cb36799c8ae084104ff0b5>, and reland with this hunk? That way if a revert is necessary in the future, it's only one. Also so that before/after metrics are together and not across two separate patches.
