Aurelien Jarno 244b1e81f6 tcg/arm: add bswap ops ...

Add an bswap16 and bswap32 ops, either using the rev and rev16
instructions on ARMv6+ or shifts and logical operations on previous
ARM versions. In both cases the result use less instructions than
the pure TCG version.

These ops are also needed by the qemu_ld/st functions.
