Add HUGE_VAL macros for more _FloatN, _FloatNx types.
This patch continues the preparation for additional _FloatN / _FloatNx type support by adding appropriately conditional definitions of HUGE_VAL_* macros, corresponding to the HUGE_VAL_F128 definition already present. Tested for x86_64. * math/math.h [__HAVE_FLOAT16 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (HUGE_VAL_F16): New macro. [__HAVE_FLOAT32 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (HUGE_VAL_F32): Likewise. [__HAVE_FLOAT64 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (HUGE_VAL_F64): Likewise. [__HAVE_FLOAT32X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (HUGE_VAL_F32X): Likewise. [__HAVE_FLOAT64X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (HUGE_VAL_F64X): Likewise. [__HAVE_FLOAT128X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (HUGE_VAL_F128X): Likewise.
