[PATCH] D80525: [clangd] Fix crash-bug in preamble indexing when using modules.

[Adam Czachorowski via Phabricator via cfe-commits]

adamcz added a comment.

Resurrecting this, with the ignore #undef when #define is in a module approach. Still worth having a test, especially that it's the first test we have for modules.

Note that the test code changed since last version due to introduction of ThreasafeFS since my original change.
