The new-in-ARMv8 YIELD instruction has been implemented to throw an EXCP_YIELD back up to the QEMU main loop. In system emulation we use this to decide to schedule a different guest CPU in SMP configurations. In usermode emulation there is nothing to do, so just ignore it and resume the guest. This prevents an abort with "unhandled CPU exception 0x10004" if the guest process uses the YIELD instruction.

bswap_code is a CPU property of sorts ("is the iside endianness the opposite way round to TARGET_WORDS_BIGENDIAN?") but it is not the actual CPU state involved here which is SCTLR.B (set for BE32 binaries, clear for BE8). Replace bswap_code with SCTLR.B, and pass that to arm_ld*_code. The next patches will make data fetches honor both SCTLR.B and CPSR.E appropriately.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).
