[PATCH 2/4] [Powerpc] tune/optimize memmove/wordcopy. Remove switch statement.

[Will Schmidt]

[Powerpc] tune/optimize memmove/wordcopy. Remove switch statement.

With the merge helper macros in place, accepting the alignment value
directly, we no longer need the alignment switch statement, so remove it.

2012-04-03  Will Schmidt <will_schmidt@vnet.ibm.com>

	* sysdeps/powerpc/powerpc64/power6/wordcopy.c: Remove switch statement.
	* sysdeps/powerpc/powerpc32/power6/wordcopy.c: Likewise.
