1263d6429d rs6000: New type attribute value "halfmul" 
This is for the legacy integer multiply-accumulate instructions.
Quite a mouthful, and "mulhw" is also a terrible name since we already
have a machine instruction called exactly that.  Hence "halfmul".

Also fixes the titan automaton description for this.
