Add optimized sinf and cosf routines for x86 and x86-64
* sysdeps/i386/i686/fpu/multiarch/Makefile (sysdep_routines): Add s_sinf-sse2, s_conf-sse2. * sysdeps/i386/i686/fpu/multiarch/s_sinf-sse2.S: New file. * sysdeps/i386/i686/fpu/multiarch/s_cosf-sse2.S: New file. * sysdeps/i386/i686/fpu/multiarch/s_sinf.c: New file. * sysdeps/i386/i686/fpu/multiarch/s_cosf.c: New file. * sysdeps/ieee754/flt-32/s_sinf.c (SINF, SINF_FUNC): Add macros for using routine as __sinf_ia32. Use macro for function declaration and weak_alias. * sysdeps/ieee754/flt-32/s_cosf.c (COSF, COSF_FUNC): Add macros for using routine as __cosf_ia32. Use macro for function declaration and weak_alias. * sysdeps/i386/i686/fpu/multiarch/e_expf-sse2.S: Fix Copyright. * sysdeps/i386/i686/fpu/multiarch/e_expf.c: Fix Copyright. * 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. * math/libm-test.inc (cos_test): Add more test cases. (sin_test): Likewise. (sincos_test): Likewise.
