Output: Generate MethodType and OffsetType elements

Implement the OutputMemberPointerType method.  If a type is a pointer to
a data member, call a new OutputOffsetType method to generate an
OffsetType element representing it directly.  If a type is a pointer to
a function member, queue a DumpType node that holds the pointee function
type and the containing class.  Teach the main OutputType method to
recognize this case and dispatch to a new OutputMethodType method to
generate a MethodType element.
