target-microblaze: Cleanup dec_mul
Use tcg_gen_mul_tl for muli and mul instructions.
Use tcg_gen_muls2_tl for mulh instruction.
Use tcg_gen_mulu2_tl for mulhu instruction.
Use tcg_gen_mulsu2_tl for mulhsu instruction.
Note that this last fixes a bug, in that mulhsu was
previously treating both operands as signed, instead
of treating rb as unsigned.
