This fixes a crash where no IRGenModule was found for the macro expansion SourceFile of a macro attached to a node imported from clang. Normally this would not trigger since there's an early exit when only a single IGM exists, so it requires multiple outputs and threads to trigger. Resolves #88864 rdar://176347021

// Regression test: this used to trigger a compiler crash in IRGenerator::getGenModule
|
|
// since the SourceFile for the _SwiftifyImport macro expansion had no corresponding
|
|
// IRGenModule. This would only trigger with multiple outputs and multiple threads
|
|
// since there's only a single IRGenModule to return otherwise.
