[PATCH 13/14] [x86_64] Vector math functions (sincos and tests)

[Andrew Senkevich <andrew dot n dot senkevich at gmail dot com>]

Hi,

here is implementation of vectorized sincos containing SSE, AVX,
AVX2 and AVX512 versions according to Vector ABI
<https://groups.google.com/forum/#!topic/x86-64-abi/LmppCfN1rZ4>.

        * NEWS: Mention addition of x86_64 vector sincos.
        * bits/libm-simd-decl-stubs.h: Added stubs for sincos.

        * math/bits/mathcalls.h: Added sincos declaration with __MATHDECL_VEC.
        * math/gen-libm-have-vector-test.sh: Added generation of sincos wrapper
        declaration under condition.
        * math/test-vec-loop.h (TEST_VEC_LOOP): Refactored.
