[SCEV] SCEVPtrToIntExpr simplifications

If we've got an SCEVPtrToIntExpr(op), where op is not an SCEVUnknown,
we want to sink the SCEVPtrToIntExpr into an operand,
so that the operation is performed on integers,
and eventually we end up with just an `SCEVPtrToIntExpr(SCEVUnknown)`.

[MachineInstr] Add support for instructions with multiple memory operands.

- Basically iterate each pair of memory operands from both instructions
  and return true if any of them may alias.
- The exception are memory instructions without any memory operand. They
  may touch everything and could alias to any memory instruction.
