  [CIR] Fix spurious MemRead on pure pointer-arithmetic ops

Remove incorrect [MemRead] annotations from ops that only perform
pointer arithmetic without loading memory. Add Pure trait to ops
that were missing it.

Affected ops:
- VTableGetVPtrOp, VTableGetVirtualFnAddrOp, VTableGetTypeInfoOp:
  remove [MemRead] (already had Pure)
- GetMemberOp, GetRuntimeMemberOp, BaseClassAddrOp, DerivedClassAddrOp:
  remove [MemRead] and add Pure
