Add definitions for rvalue reference types
This patch introduces preliminal definitions regarding C++11 rvalue references
to the gdb type system. In addition to an enum type_code entry, a field in
struct type and an accessor macro for that which are created similarly to the
lvalue references counterparts, we also introduce a TYPE_REFERENCE convenience
macro used to check for both kinds of references simultaneously as they are
equivalent in many contexts.
