  [NFC][llvm][MIRVRegNamerUtils] Refactoring GetHashableMO into switch-statement.

This refactors the if-statements handling the hashing of various
MachineOperand types into a switch-statement. The purpose is to cover
all the basis for all MachineOperand types while being very deliberate
about which MachineOperand types we are not handling and why (better
added comments). This patch is a NFC redo of https://reviews.llvm.org/D71396.
Much of the changes present in D71396 will come in smaller follow-up patches
that will add support for hashing the MachineOperand types that aren't
covered piece-meal with tests for each new case.
