Type::isObjectType now implements the (more sensible) C++ definition
of "object type" rather than the C definition of "object type". The
difference is that C's "object type" excludes incomplete types such as
struct X;
However, C's definition also makes it far too easy to use isObjectType
as a means to detect incomplete types when in fact we should use other
means (e.g., Sema::RequireCompleteType) that cope with C++ semantics,
including template instantiation.
I've already audited every use of isObjectType and isIncompleteType to
ensure that they are doing the right thing for both C and C++, so this
is patch does not change any functionality.
