7cabf9d02c - Let MachineInstr ctors add implicit def and use operands. Other operands
will be inserted before these operands. If the opcode changes (by
  setOpcode), the implicit operands are updated as well.
- Added IsKill, IsDead fields to MachineOperand in preparation for changes
  that move kill / dead info to MachineInstr's.

f5bffa5670 Running with frame pointers prevented debugging, external probes and
potentially some system calls/exception handling from working.  TOS must always
link to previous frame.  This is a short term workaround until alloca scheme is
reworked.

1409347c13 allow the offset of a preinc'd load to be the low-part of a global. This
produces this clever code:

_millisecs:
        lis r2, ha16(_Time.1182)
        lwzu r3, lo16(_Time.1182)(r2)
        lwz r2, 4(r2)
        addic r4, r2, 1
        addze r3, r3
        blr

instead of this:

_millisecs:
        lis r2, ha16(_Time.1182)
        la r3, lo16(_Time.1182)(r2)
        lwz r2, lo16(_Time.1182)(r2)
        lwz r3, 4(r3)
        addic r4, r3, 1
        addze r3, r2
        blr

for:

long %millisecs() {
        %tmp = load long* %Time.1182            ; <long> [#uses=1]
        %tmp1 = add long %tmp, 1                ; <long> [#uses=1]
        ret long %tmp1
}

ae1f3758bd Don't dag combine floating point select to max and min intrinsics. Those
take v4f32 / v2f64 operands and may end up causing larger spills / restores.
Added X86 specific nodes X86ISD::FMAX, X86ISD::FMIN instead.

3a017e8abd Fix a bug in SelectScalarSSELoad. Since the load is wrapped in a
SCALAR_TO_VECTOR, even if the hasOneUse() check pass we may end up folding
the load into two instructions. Make sure we check the SCALAR_TO_VECTOR
has only one use as well.

1604b6a873 add an initial cut at preinc loads for ppc32. This is broken for ppc64
(because the 64-bit reg target versions aren't implemented yet), doesn't
support r+r addr modes, and doesn't handle stores, but it works otherwise. :)

This is disabled unless -enable-ppc-preinc is passed to llc for now.
