Not sure "recovery mode" is well-defined enough to refer to in this way
maybe:
When there are errors resolving types, clang may use IntTy as a fallback,
breaking our assumption that function declarations have function types.
(I thought there was a name for this usage of IntTy but I can't find one. It
happens e.g. at GetFullTypeForDeclarator, SemaType.cpp:5734)
