PowerPC64 ENTRY_TOCLESS

A number of functions in the sysdeps/powerpc/powerpc64/ tree don't use
or change r2, yet declare a global entry that sets up r2.  This patch
fixes that problem, and consolidates the ENTRY and EALIGN macros.

	* sysdeps/powerpc/powerpc64/sysdep.h: Formatting.
	(NOPS, ENTRY_3): New macros.
