[PATCH] Mark inputs being ZERO as unlikely __mul in powerpc

[Siddhesh Poyarekar]

Hi,

The patch below marks the case of X or Y being ZERO as unlikely on
powerpc.  This makes no difference to the generated code.  The only
purpose is to sync up the code with the default code.  OK to commit?

	* sysdeps/powerpc/powerpc32/power4/fpu/mpa.c (__mul): Mark X
	or Y being zero as being unlikely.
	* sysdeps/powerpc/powerpc64/power4/fpu/mpa.c (__mul):
	Likewise.
