[PATCH] D65428: Remove cache for macro arg stringization

[Reid Kleckner via Phabricator via cfe-commits]

rnk created this revision.
rnk added reviewers: vsk, rsmith.
Herald added a project: clang.

The cache recorded the wrong expansion location for all but the first
stringization. It seems uncommon to stringize the same macro argument
multiple times, so this cache doesn't seem that important.

Fixes PR39942
