Anna Thomas 2bc129c5fd [StatepointsForGC] Rematerialize in the presence of PHIs ...

Summary:
While walking the use chain for identifying rematerializable values in RS4GC,
add the case where the current value and base value are the same PHI nodes.

This will aid rematerialization of geps and casts instead of relocating.
