I don't need to implement this quite yet - and not for ConstantInt anyhow.

at them since they'd end up in the register weights list. Tell it to stop

moment, as there's a testcase that uses it and expects it
to be subject to optimizations; we won't be doing that.
Some adjustments based on feedback from Bill.

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
