Remove a test case that no longer makes sense.

This was testing the handling of sub-register coalescing followed by
remat.  The original problem was caused by the extra <imp-def> operands
added by sub-register coalescing.  Those <imp-def> operands are not
added any longer, and the test case passes even when the original patch
is reverted.
