Joseph Myers cc6a8d7457 Add totalordermag, totalordermagf, totalordermagl. 
In addition to the totalorder functions, TS 18661-1 defines
totalordermag functions, which do the same comparison but on the
absolute values of the arguments.  This patch implements these
functions for glibc, including the type-generic macro in <tgmath.h>.
In general the implementations are similar to but simpler than those
for the totalorder functions.

Tested for x86_64, x86, mips64 and powerpc.

	* math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)]
	(totalordermag): New declaration.
	* math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (totalordermag):
	New macro.
	* math/Versions (totalordermag): New libm symbol at version
	GLIBC_2.25.
	(totalordermagf): Likewise.
	(totalordermagl): Likewise.
	* math/Makefile (libm-calls): Add s_totalordermagF.
	* math/libm-test.inc (totalordermag_test_data): New array.
	(totalordermag_test): New function.
	(main): Call totalordermag_test.
	* math/test-tgmath.c (NCALLS): Increase to 125.
	(F(compile_test)): Call totalordermag.
	(F(totalordermag)): New function.
	* manual/arith.texi (FP Comparison Functions): Document
	totalordermag, totalordermagf and totalordermagl.
	* manual/libm-err-tab.pl: Update comment on interfaces without
	ulps tabulated.
