c1fb0473ed Adding more arithmetic operators to MMX. This is an almost exact copy of
the addition. Please let me know if you have suggestions.

2f88dcdfb3 Added "padd*" support for MMX. Added MMX move stuff to X86InstrInfo so that
moves, loads, etc. are recognized.

df5cdb5288 in X86-64 CCC, i8/i16 arguments are already properly zext/sext'd on input.
Capture this so that downstream zext/sext's are optimized out.  This
compiles:
  int test(short X) { return (int)X; }

to:

_test:
        movl %edi, %eax
        ret

instead of:

_test:
        movswl %di, %eax
        ret


GCC produces this bizarre code:

_test:
        movw    %di, -12(%rsp)
        movswl  -12(%rsp),%eax
        ret

c30654cc96 Fix an X86-64 abi bug. We now compile:

        movswl %di, %edi
        call _foo
        addq $8, %rsp

instead of:

_bar:

values out.

cb18656734 simplify result value lowering by splitting the selection of *where* to return
registers out from the logic of *how* to return them.

This changes X86-64 to mark EAX live out when returning a 32-bit value,
where before it marked RAX liveout.
