Hi Ian,

The coroutines implementation introduces a new operator with a
mangling of 'aw'.  This patch adds that to libiberty's demangler.

Although this is presented as part of the coroutines patch series
it could stand alone, since clang and EDG-based compilers are
already emitting this mangling.

I tested this with a binutils build (using the built c++filt).

OK for trunk?
Iain
