PATCH x86_64 only: optimize sinf and cosf with SSE2

[Dmitrieva Liubov]

I've fixed the sinf and cosf x86_64 patch according to requests below
and reattach it.

And yes, I intend to provide SSE optimized sincos in couple weeks for
the patch: http://sourceware.org/ml/libc-alpha/2012-06/msg00692.html

Change log is the same:

2012-08-13  Liubov Dmitrieva  <liubov.dmitrieva@gmail.com>

       * sysdeps/x86_64/fpu/s_sinf.S New file.
       * sysdeps/x86_64/fpu/s_cosf.S New file.
       * sysdeps/x86_64/fpu/libm-test-ulps Update.
