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.
