[GVN] Restrict equality propagation for pointers (#82458) 
This patch does the following:

Adds the following functions:
- replaceDominatedUsesWithIf() that takes a callback.

- canReplacePointersIfEqual(...) returns true if the underlying object
is the same, and for null and const dereferencable pointer replacements.

- canReplacePointersIfEqualInUse(...) returns true for the above as well
as if the use is in icmp/ptrtoint or phi/selects feeding into them.

Updates GVN using the functions above so that the pointer replacements
are only made using the above API.
