Fix crash parsing invalid code
The code in the test caused a crash with this backtrace:
RecordLayoutBuilder.cpp:2934: const clang::ASTRecordLayout &clang::ASTContext::getASTRecordLayout(const clang::RecordDecl *) const: Assertion `!D->isInvalidDecl() && "Cannot get layout of invalid decl!"' failed.

Fixing by bailing out for invalid classes.
