MIPS64: Fix code generator and simulator for DEXTM.

MIPS64: Fix code generator and simulator for DEXTM.

In code generator, DEXTM instruction will be emitted for intervals
position=[0,31] and size=[33,64]. In simulator, mask for DEXTM will be
calculated on correct way for size = 64. Disassembler has now possibility
to disassemble instructions DEXTM and DEXTU.
