PATCH: Improve 32bit strcpy functions with SSE2/SSSE3

From: "H.J. Lu" <hongjiu dot lu at intel dot com>
To: GNU C Library <libc-alpha at sourceware dot org>
Date: Wed, 22 Jun 2011 13:36:00 -0700
Subject: PATCH: Improve 32bit strcpy functions with SSE2/SSSE3
Reply-to: "H.J. Lu" <hjl dot tools at gmail dot com>
Hi,

This patch improves 32bit strcpy functions with SSE2 and SSSE3.  Tested
on Atom, Core 2 and Core i7.  It improves performance by up to 15X.
