3b473fecdf PowerPC: multiarch bzero cleanup for PPC64
This patch cleanups the multiarch bzero for powerpc64 by remove
the multiarch objects and use instead the the memset embedded
implementation presented in each multiarch optimization.  The
code generate is essentially the same, but the TB_TOCLESS (which
is not essential).

3be87c77d2 PowerPC LE memset
http://sourceware.org/ml/libc-alpha/2013-08/msg00104.html

One of the things I noticed when looking at power7 timing is that rlwimi
is cracked and the two resulting insns have a register dependency.
That makes it a little slower than the equivalent rldimi.

	* sysdeps/powerpc/powerpc64/memset.S: Replace rlwimi with
        insrdi.  Formatting.
	* sysdeps/powerpc/powerpc64/power4/memset.S: Likewise.
