Fix a crash on invalid code.
The diagnostic was attempting to access the QualType of a TypeDecl by calling
TypeDecl::getTypeForDecl. However, the Type pointer stored there is lazily
loaded by functions in ASTContext. In most cases, the pointer is loaded and
this does not cause a problem. However, when more that 50 or so unknown types
are seen beforehand, this causes the Type to not be loaded, passing a null
Type to the diagnostics, leading to the crash. Using
ASTContext::getTypeDeclType will give a proper QualType for all cases.
