float128: Add public _Float128 declarations to libm.

This introduces the machine-dependent bits/floatn.h to control
the inclusion of _Float128 ABI.

* bits/floatn.h: New file.
* bits/huge_val_flt128.h: Likewise.

* bits/libm-simd-decl-stubs.h (__DECL_SIMD_cosf128): New macro.
(__DECL_SIMD_sinf128): Likewise.
(__DECL_SIMD_sincosf128): Likewise.
(__DECL_SIMD_logf128): Likewise.
(__DECL_SIMD_expf128): Likewise.
(__DECL_SIMD_powf128): Likewise.

* math/Makefile (headers): Install bits/floatn.h and
bits/huge_val_flt128.h.

* math/bits/cmathcalls.h (_Mdouble_complex_): Only define if not
defined.

* math/bits/mathcalls.h (pow10, isinf, finite, drem, significand)
(isnan, gamma, nexttoward, scalb): Only define if not
__MATH_DECLARING_FLOATN.
(nextdown, nextup, llogb, roundeven, fromfp, ufromfp, fromfpx)
(ufromfpx, fmaxmag, fminmag, totalorder, totalordermag)
(canonicalize, getpayload, setpayload, setpayloadsig): Declare for
_FloatN even if __STDC_WANT_IEC_60559_BFP_EXT__ is not defined.

* math/complex.h: Include bits/libc-header-start.h and bits/floatn.h.
Include bits/cmathcalls.h to get the declarations of _Float128
versions of complex functions.
[__HAVE_FLOAT128 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (CMPLXF128):
Define macro.

* math/math.h: Include bits/floatn.h and bits/huge_val_flt128.h.
Include bits/mathcalls-helper-functions.h and bits/mathcalls.h to
get the declarations of _Float128 versions of math functions.
(__MATH_DECLARING_FLOATN): New macro to control declaration of
_FloatN types.
[__GNUC_PREREQ (6,0)] (signbit): Since GCC 6.0, __builtin_signbit
is type-generic, so use it without __MATH_TG.
[__HAVE_DISTINCT_FLOAT128] (isinf): This builtin is broken for
_Float128 type on GCC < 7.0.  Explicitly call __isinff128 for
_Float128 type and GCC < 7.0, otherwise use the builtin.
[__HAVE_FLOAT128 && defined __USE_GNU] (M_Ef128, M_LOG2Ef128)
(M_LOG10Ef128, M_LN2f128, M_LN10f128, M_PIf128, M_PI_2f128)
(M_PI_4f128, M_1_PIf128, M_2_PIf128, M_SQRT2f128, M_SQRT1_2f128):
New _GNU_SOURCE enabled macros.
