target/mips: Add unaligned access support for MIPS64R6 and Loongson-3
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.
