I've done a bit of debugging to find the source of the crash:
Sema::LazilyCreateBuiltin() calls Sema::PushOnScopeChains() passing
Sema.TUScope, and PushOnScopeChains() doesn't test for nullptr.
It appears that TUScope is always null (or at least by the time of the
first check for error-free instantiation it is null). Is this expected?
