188da252ab Tweak to ignoring reserved regs. The allocator was occasionally still looking 
at them since they'd end up in the register weights list. Tell it to stop
doing that.

to be subject to optimizations; we won't be doing that.

29c353b9c3 Using target specific nodes for shuffle nodes makes the mask 
check more strict, breaking some cases not checked in the
testsuite, but also exposes some foldings not done before,
as this example:

  movaps  (%rdi), %xmm0
  movaps  (%rax), %xmm1
  movaps  %xmm0, %xmm2
  movss %xmm1, %xmm2
  shufps  $36, %xmm2, %xmm0

now is generated as:

  movaps  (%rdi), %xmm0
  movaps  %xmm0, %xmm1
  movlps  (%rax), %xmm1
  shufps  $36, %xmm1, %xmm0

This caused a miscompilation in WebKit where %RAX had conflicting defs when
RemoveCopyByCommutingDef was commuting a %EAX use.
