When checking whether we can load a bridging precompiled header (PCH), we end up parsing module maps. If Clang emits a warning or error while parsing the module maps we encounter, the Swift compiler would crash because we have not properly established the invariants of Clang's diagnostic engine. Perform a pairsed set of BeginSourceFile/EndSourceFile calls on the Clang diagnostic consumer to set up the appropriate state. Fixes rdar://problem/57626886.
