[LLVMdev] Register Alias Sets
I notice that in X86GenRegisterInfo.inc, the AliasSets do not

const unsigned RAX_AliasSet[] = { X86::EAX, X86::AX, X86::AL, X86::AH,
0 };
const unsigned EAX_AliasSet[] = { X86::RAX, X86::AX, X86::AL,
X86::AH, 0 };

equivalent alias sets but one wouldn't know that from
