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?

	* config/rs6000/rs6000.h (CALL_REALLY_USED_REGISTERS): Do not
	include MQ.
