… file has errors. We were checking the parent invocation's DiagnosticEnginer rather than the subinstance's to determine if there were any errors building the module, which meant we would fail to load the module if there were errors prior to the import statement in the importing file. This also meant code completion would fail to load the module, because it always emits a bogus error in order to mark the AST as erroneous so that different parts of the compiler (e.g. the verifier) have less strict assumptions. rdar://problem/43906499
…langImporter option on the sub invocation if it's set on the parent In addition to capturing more detailed preprocessor info, the DetailedPreprocessorRecord option sets the clang module format to 'raw' rather than the default 'object'. Sourcekitd doesn't link the code generation libs, which it looks like the default 'object' format requires, so it sets this option to true. The subinvocation generated when loading a module from a .swiftinterface file still used the default prior to this change though, so it would end up crashing sourcekitd. This change sets the DetailedProccessorRecord option if the DetailedRecord option is set on the preprocessor options of parent context's clang module loader. This fixes interface generation crashing for modules that only have a .swiftinterface file. rdar://problem/43906499
