In a function argument, we handle a typedef for a pointer specially, using the pointer type rather than the typedef, to permit the Go calls to match the laxer type conversions permitted in C. We record the typedef so that we use that type in the C code, in case it has a special attribute. However, using the typedef is wrong when using a pointer to a basic type, because the C code may sometimes use the typedef and sometimes not, and using the typedef in all cases will cause incorrect type errors on the Go side. Fortunately we only really need to use the typedef when pointing to a struct/union/class, and in such a case confusion is unlikely. Fixes #17723.
