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

Update tests.  Add auto-upgrade support for the old intrinsics.

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

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.

This makes it possible to unregister the file from FilesToRemove when
the file is done. Also, this eliminates the need for
formatted_tool_output_file.

landing pad into uses of registers rather than loads from a stack
slot.  Doesn't touch the 'orrible hack code - Bill needs to persuade
me harder :)

then the SSAUpdator may access freed memory.  Instead, simply pass
in the type and name explicitly, which is all that was used anyway.
