Switch clang_createTranslationUnitFromSourceFile to use ASTUnit::LoadFromCommandLine.
- This is much faster, as it avoids the overhead of dumping an AST file to disk and reloading it.
- For debugging purposes, there is a clang_setUseExternalASTGeneration hook which can be used to disable this.
On the Sketch Cocoa app, the speedup is pretty nice, especially when using a PCH file while scanning the source:
Wall time to c-index-test all files (no PCH):
Old: 23.4221
New: 12.3884
Wall time to c-index-test all files (with a PCH, and "local" mode):
Old: 10.9233
New: 1.9038
