Add the necessary bits to the private headers to support building the _Float128 libm functions. A local override for float.h is provided to include the missing *FLT128 macros implied by TS 18661-3 for this type when compiling prior to GCC 7. * include/complex.h (__kernel_casinhf128): New declaration. * include/float.h: New file. * include/math.h (__finitef128): Add a hidden def. (__isinff128): Likewise. (__isnanf128): Likewise. (__fpclassify): Likewise. (__issignalling): Likewise. (__expf128): Likewise. (__expm1f128): Likewise. * sysdeps/generic/fix-fp-int-convert-overflow.h: (FIX_FLT128_LONG_CONVERT_OVERFLOW): New macro. (FIX_FLT128_LLONG_CONVERT_OVERFLOW): Likewise. * sysdeps/generic/math-type-macros-float128.h: New file. * sysdeps/generic/math_private.h: Include bits/floatn.h and math_private_calls.h for _Float128. (__isinff128): New inline implementation used when GCC < 7.0, since in this case __builtin_isinf_sign is broken. (fabsf128): New inline implementation that calls the builtin. (__EXPR_FLT128): New macro. (min_of_type): Optionally include _Float128 types too. * sysdeps/generic/math_private_calls.h (__kernel_sincos): Declare for _Float128. (__kernel_rem_pio2): Likewise. * sysdeps/ieee754/ldbl-opt/s_sin.c: (__DECL_SIMD_sincos_disablef128): New macro.
