Anna Thomas 25f28db283 [SafepointIRVerifier] Avoid false positives in GC verifier for compare between pointers 
Today the safepoint IR verifier catches some unrelocated uses of base
pointers that are actually valid.

With this change, we narrow down the set of false positives.
Specifically, the verifier knows about compares to null and compares
between 2 unrelocated pointers.
