Add SNAN macros for more _FloatN, _FloatNx types.
This patch continues the preparation for additional _FloatN / _FloatNx type support by adding appropriately conditional definitions of SNAN* macros, corresponding to the SNANF128 definition already present. Tested for x86_64. * math/math.h [__HAVE_FLOAT16 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (SNANF16): New macro. [__HAVE_FLOAT32 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (SNANF32): Likewise. [__HAVE_FLOAT64 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (SNANF64): Likewise. [__HAVE_FLOAT32X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (SNANF32X): Likewise. [__HAVE_FLOAT64X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (SNANF64X): Likewise. [__HAVE_FLOAT128X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (SNANF128X): Likewise.
