Consistently use MemoryLocation::UnknownSize to indicate unknown access size
1. Change the software pipeliner to use unknown size instead of dropping
memory operands. It used to do it before, but MachineInstr::mayAlias
did not handle it correctly.
2. Recognize UnknownSize in MachineInstr::mayAlias.
3. Print and parse UnknownSize in MIR.
