Declare most TS 18661-1 interfaces for C2X.

C2X adds the interfaces from TS 18661-1, and all except a handful in Annex F are unconditionally visible in C2X rather than only visible when __STDC_WANT_IEC_60559_BFP_EXT__ is defined. This patch updates glibc headers accordingly: most uses of __GLIBC_USE (IEC_60559_BFP_EXT) are changed to a new __GLIBC_USE (IEC_60559_BFP_EXT_C2X). (Regarding totalorder and totalordermag, the type-generic macros in tgmath.h will go away when the functions are changed to take pointer arguments.) * bits/libc-header-start.h (__GLIBC_USE_IEC_60559_BFP_EXT): Update comment. (__GLIBC_USE_IEC_60559_BFP_EXT_C2X): New macro. * bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Change to [__GLIBC_USE (IEC_60559_BFP_EXT_C2X)]. * include/limits.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * math/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * stdlib/bits/stdlib-ldbl.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * stdlib/stdint.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * stdlib/stdlib.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/aarch64/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/alpha/fpu/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/arm/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/csky/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/hppa/fpu/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/ia64/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/m68k/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/microblaze/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/mips/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/nios2/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/powerpc/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/riscv/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/s390/fpu/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/sh/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/sparc/fpu/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * sysdeps/x86/fpu/bits/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise, except for totalorder, totalordermag, getpayload, setpayload and setpayloadsig. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Likewise, except for totalorder and totalordermag.
