8e96b93aa7 Speed up x86-64 strcasestr a bit moew.
Using the new SSE4.2 instructions is cool but not really the fastest.
Some older SSE instructions can do the trick faster.

6fb8cbcb58 Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7
This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and
Core i7.  It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and
up to 1X on Core i7.  It also improves memmove by up to 3X on Atom, up to
4X on Core 2 and up to 2X on Core i7.

5a4eb7282e Remove ENABLE_SSSE3_ON_ATOM.
It turns that SSSE3 isn't slow on Atom. The problem is bsf. This patch
removes ENABLE_SSSE3_ON_ATOM.

02cea47161 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.

6f6f1215f6 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.

9a1d2d4555 Prepare use if IFUNC functions outside libc.so.
We use a callback function into libc.so to get access to the data
structure with the information and have special versions of the test
macros which automatically use this function.

e83c1a8a72 Refine testing for xmm/ymm register use in x86-64 ld.so.
The test now takes the callgraph into account.  Only code called
during runtime relocation is affected by the limitation.  We now
determine the affected object files as closely as possible from
the outside.  This allowed to remove some the specializations
for some of the string functions as they are only used in other
code paths.

16d2ea4c82 Make sure no code in ld.so uses xmm/ymm registers on x86-64.
This patch introduces a test to make sure no function modifies the
xmm/ymm registers.  With the exception of the auditing functions.

The test is probably too pessimistic.  All code linked into ld.so
is checked.  Perhaps at some point the callgraph starting from
_dl_fixup and _dl_profile_fixup is checked and we can start using
faster SSE-using functions in parts of ld.so.
