Run RTP after GVN to remove more NullCheck instructions
After GVN, we deduplicate instructions and we might have more
information regarding the nullability of the SSA variable. We can
run RTP to insert the BoundType instructions, which will later be
used by InstructionSimplifier to remove the NullCheck. RTP will be
run conditionally, only if GVN did at least one replacement.
It improves ~0.1% of odex size for speed compiled apps.
