Matt Arsenault 1cb6ce6960 TRI: Add hook to pass scavenger during frame elimination
The scavenger was not passed if requiresFrameIndexScavenging was
enabled. I need to be able to test for the availability of an
unallocatable register here, so I can't create a virtual register for
it.

It might be better to just always use the scavenger and stop
creating virtual registers.
