memory: inline and optimize devend_memop
devend_memop can rely on the fact that the result is always either 0 or MO_BSWAP, corresponding respectively to host endianness and the opposite. Native (target) endianness in turn can be either the host endianness, in which case MO_BSWAP is only returned for host-opposite endianness, or the opposite, in which case 0 is only returned for host endianness. With this in mind, devend_memop can be compiled as a setcond+shift for every target. Do this and, while at it, move it to include/exec/memory.h since !NEED_CPU_H files do not (and should not) need it.
