MIPSR6 (not only MIPS32R6) processors support unaligned access in hardware, so set MO_UNALN in their default_tcg_memop_mask. Btw, new Loongson-3 (such as Loongson-3A4000) also support unaligned access, since both old and new Loongson-3 use the same binaries, we can simply set MO_UNALN for all Loongson-3 processors.
