Support multiarch for i686. This patch adds multiarch support when configured for i686. I modified some x86-64 functions to support 32bit. I will contribute 32bit SSE string and memory functions later.

Add x86 32-bit SSE4.2 string functions. This patch adds 32bit SSE4.2 string functions. It uses -16L instead of 0xfffffffffffffff0L, which works for both 32bit and 64bit long. Tested on 32bit Core i7 and Core 2.

Remove use of SSE4.2 functions for strstr on i686 The SSE4.2 have been removed from x86_64 by commit 584b18eb. This patch fixes the build on i686, which attempts to use the removed files.

i386: memcpy functions with SSE2 unaligned load/store These new memcpy functions are the 32-bit version of x86_64 SSE2 unaligned memcpy. Memcpy average performace benefit is 18% on Silvermont, other platforms also improved about 35%, benchmarked on Silvermont, Haswell, Ivy Bridge, Sandy Bridge and Westmere, performance results attached in https://sourceware.org/ml/libc-alpha/2014-07/msg00157.html * sysdeps/i386/i686/multiarch/bcopy-sse2-unaligned.S: New file. * sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S: Likewise. * sysdeps/i386/i686/multiarch/memmove-sse2-unaligned.S: Likewise. * sysdeps/i386/i686/multiarch/mempcpy-sse2-unaligned.S: Likewise. * sysdeps/i386/i686/multiarch/bcopy.S: Select the sse2_unaligned version if bit_Fast_Unaligned_Load is set. * sysdeps/i386/i686/multiarch/memcpy.S: Likewise. * sysdeps/i386/i686/multiarch/memcpy_chk.S: Likewise. * sysdeps/i386/i686/multiarch/memmove.S: Likewise. * sysdeps/i386/i686/multiarch/memmove_chk.S: Likewise. * sysdeps/i386/i686/multiarch/mempcpy.S: Likewise. * sysdeps/i386/i686/multiarch/mempcpy_chk.S: Likewise. * sysdeps/i386/i686/multiarch/Makefile (sysdep_routines): Add bcopy-sse2-unaligned, memcpy-sse2-unaligned, memmove-sse2-unaligned and mempcpy-sse2-unaligned. * sysdeps/i386/i686/multiarch/ifunc-impl-list.c (MAX_IFUNC): Set to 4.

Remove configure tests for SSE4 support. GCC added support for -msse4 in version 4.3. Thus the configure tests for it are obsolete, and this patch removes them.
