expr.c (emit_block_move_via_movmem): Fix expected_align parameter.

2008-07-08  Raksit Ashok  <raksit@google.com>

	* expr.c (emit_block_move_via_movmem): Fix expected_align parameter.
	(set_storage_via_setmem): Fix expected_align parameter.
	* doc/invoke.texi (i386 and x86-64 Options): Add a couple of options
	missing from the list.
	* doc/md.texi (movmem): Explicitly state that expected alignment is
	to be expressed in bytes.
	(setmem): Explicitly state that expected alignment is to be expressed
	in bytes.
