[Bug rtl-optimization/15023] -frename-registers is slow

Haven't seen any reports of wrong-code coming out of register renaming in a
while. Register renaming is enabled if loop unrolling / peeling is enabled.  So
the test coverage of this pass is much better than it used to be.  I think that
the wrong-code issue for this bug is fixed.
