[cxx-abi-dev] C++0x: Mangling of rvalue reference types

Generating this is easy.  Demangling would need a simple look ahead to
look for both.

Would using up another capital letter solve this trivial issue and save
more space?  We could use "B".  ;-)

(We do have two letter combos in TV TT TI TS and in ctor/dtor names.)
