[CodeGen] Refactor MachineMemOperand's Flags enum.
Summary:
- Give it a shorter name (because we're going to refer to it often from
SelectionDAG and friends).
- Split the flags and alignment into separate variables.
- Specialize FlagsEnumTraits for it, so we can do bitwise ops on it
without losing type information.
- Make some enum values constants in MachineMemOperand instead.
MOMaxBits should not be a valid Flag.
- Simplify some of the bitwise ops for dealing with Flags.
