1c6191ffe7 Add a hacky workaround for crashes due to vectors live across blocks. 
Note that this code won't work for vectors that aren't legal on the
target.  Improvements coming.

a5de484bc7 Split the list scheduler into top-down and bottom-up pieces. The priority 
function of the top-down scheduler are completely bogus currently, and
having (future) PPC specific in this file is also wrong, but this is a
small incremental step.

cffbb5174f Dumb bug. Code sees a memcpy from X+c so it increments src offset. But it 
turns out not to point to a constant string but it forgot change the offset
back.

298ebf2bd8 If the false case is the current basic block, then this is a self loop. 
We do not want to emit "Loop: ... brcond Out; br Loop", as it adds an extra
instruction in the loop.  Instead, invert the condition and emit
"Loop: ... br!cond Loop; br Out.

Generalize the fix by moving it from PPCDAGToDAGISel to SelectionDAGLowering.
