History
Joseph Myers 525f803984 Add fmaxmag, fminmag functions. 
TS 18661-1 defines fmaxmag and fminmag functions that return the
argument with maximum / minimum magnitude (acting like fmax / fmin if
the arguments have the same magnitude or either argument is a NaN).
These correspond to the IEEE 754-2008 operations maxNumMag and
minNumMag.  This patch implements these functions for glibc.  They are
implemented with type-generic templates.  Tests are based on those for
fmax and fmin.

Tested for x86_64, x86, mips64 and powerpc.
