[PATCH] D15490: [libclang] Add a flag to create the precompiled preamble on the first parse.

doug.gregor added a comment.

For reference, you can test this by setting the environment variable LIBCLANG_TIMING in your test, and checking that the string "Precompiling preamble" shows up on first parse.
