Nothing uses MQ anymore, but it still shows up in all the dump files. This patch removes it from CALL_REALLY_USED_REGISTERS so that that does not happen anymore (it is still a fixed register, there should be no functional change).
Bootstrapped and regression tested on powerpc64-linux, -m32,-m64. Is this okay for trunk?
