target: [PR102941] Fix inline-asm flags with non-REG_P output

So the problem here is that arm_md_asm_adjust would
just create a set directly to the output memory which is wrong.
It needs to output to a temp register first and then do a
move.

OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions.
I have no way to test on arm even though this touches common code.
