Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.
* manual/arith.texi (Infinity and NaN): Document SNANFN and SNANFNx.
(Error Reporting by Mathematical Functions): Document HUGE_VAL_FN
and HUGE_VAL_FNx.
(Absolute Value): Document fabsfN, fabsfNx, cabsfN, cabsfNx.
Rephrase the paragraph that mentions that fabs, fabsf, and fabsl
are in math.h, to avoid having to list the _FloatN and _FloatNx
variants as well. Likewise for the cabs functions.
(Normalization Functions): Document frexpfN, frexpfNx, ldexpfN,
ldexpfNx, scalbnfN, scalbnfNx, scalblnfN, scalblnfNx.
Mention that _FloatN and _FloatNx variants of scalbn and scalbln
come from TS 18661-3, since this section explicitly states that
these functions come from BSD.
(Rounding Functions): Document ceilfN, ceilfNx, floorfN, floorfNx,
truncfN, truncfNx, rintfN, rintfNx, nearbyintfN, nearbyintfNx,
roundfN, roundfNx, roundevenfN, roundevenfNx, lrintfN, lrintfNx,

fromfpfN, fromfpfNx, ufromfpfN, ufromfpfNx, fromfpxfN, fromfpxfNx,
ufromfpxfN, ufromfpxfNx, modffN, modffNx.
(Remainder Functions): Document fmodfN, fmodfNx, remainderfN,
remainderfNx.

nextupfNx, nextdownfN, nextdownfNx, nanfN, nanfNx, canonicalizefN,
canonicalizefNx, getpayloadfN, getpayloadfNx, setpayloadfN,
setpayloadfNx, setpayloadsigfN, setpayloadsigfNx.

totalorderfNx, totalordermagfN, totalordermagfNx.
(Miscellaneous FP arithmetic functions): Document fminfN, fminfNx,
fmaxfN, fmaxfNx, fminmagfN, fminmagfNx, fmaxmagfN, fmaxmagfNx,
fdimfN, fdimfNx, fmafN, fmafNx.

_FloatNx complex.
(rojections, Conjugates, and Decomposing of Complex Numbers):
Document crealfN, crealfNx, cimagfN, cimagfNx, conjfN, conjfNx,
cargfN, cargfNx, cprojfN, cprojfNx.
* manual/math.texi (Mathematics): Mention that the _FloatN and
_FloatNx variants of the math functions come from TS 18661-3,
unless otherwise stated.
(Predefined Mathematical Constants): Document the _FloatN and
_FloatNx variants of the macros prefixed with M_.
(Trigonometric Functions): Document sinfN, sinfNx, cosfN, cosfNx,
tanfN, tanfNx, sincosfN, sincosfNx, csinfN, csinfNx, ccosfN,
