"hint" space for Thumb actually overlaps the encoding space of the CPS instruction. In actuality, hints can be defined as CPS instructions where imod and M bits are all nil. Handle decoding of permitted nop-compatible hints (i.e. nop, yield, wfi, wfe, sev) in DecodeT2CPSInstruction. This commit adds a proper diagnostic message for Imm0_4 and updates all tests.
