Changed FM classes so that they inherit from MipsR6Inst and MMR6Arch.
Changed DESC classes for DCLO, DCLZ, DSBH_DSHD so that they don't inherit from MipsR6Inst and MMR6Arch.
Added BaseOpcode to desc classes that were missing it.
Added two SHIFT_ROTATE classes to serve as DESC_BASE to all shift and rotate instructions in MM64R6.
Added CodeGen support and tests for DROTR, DROTRV, DCLZ, DCLO in MM64R6.
