Joseph Myers 0175c9e9be 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.
