Start of series of patches with x86_64 vector math functions.
Here is implementation of cos containing SSE, AVX, AVX2 and AVX512 versions according to Vector ABI which had been discussed in <https://groups.google.com/forum/#!topic/x86-64-abi/LmppCfN1rZ4>. Vector math library build and ABI testing enabled by default for x86_64. * sysdeps/x86_64/fpu/Makefile: New file. * sysdeps/x86_64/fpu/Versions: New file. * sysdeps/x86_64/fpu/svml_d_cos_data.S: New file. * sysdeps/x86_64/fpu/svml_d_cos_data.h: New file. * sysdeps/x86_64/fpu/svml_d_cos2_core.S: New file. * sysdeps/x86_64/fpu/svml_d_cos4_core.S: New file. * sysdeps/x86_64/fpu/svml_d_cos4_core_avx.S: New file. * sysdeps/x86_64/fpu/svml_d_cos8_core.S: New file. * sysdeps/x86_64/fpu/svml_d_wrapper_impl.h: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_cos2_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_cos2_core_sse4.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_cos4_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_cos4_core_avx2.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_cos8_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_cos8_core_avx512.S: New file. * sysdeps/x86_64/fpu/multiarch/Makefile (libmvec-sysdep_routines): Added build of SSE, AVX2 and AVX512 IFUNC versions. * sysdeps/x86/fpu/bits/math-vector.h: Added SIMD declaration for cos. * math/bits/mathcalls.h: Added cos declaration with __MATHCALL_VEC. * sysdeps/x86_64/configure.ac: Options for libmvec build. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/sysdep.h (cfi_offset_rel_rsp): New macro. * sysdeps/unix/sysv/linux/x86_64/libmvec.abilist: New file. * manual/install.texi (Configuring and compiling): Document --disable-mathvec. * INSTALL: Regenerated. * NEWS: Mention addition of libmvec and x86_64 vector cos.
