Implement C23 cospi

Browse source 
C23 adds various <math.h> function families originally defined in TS
18661-4.  Add the cospi functions (cos(pi*x)).

Tested for x86_64 and x86, and with build-many-glibcs.py.

@ -31,6 +31,13 @@ Major new features:
* The iconv program now supports converting files in place. The program
automatically uses a temporary file if required.
* The following ISO C23 function families (introduced in TS
18661-4:2015) are now supported in <math.h>. Each family includes
functions for float, double, long double, _FloatN and _FloatNx, and a
type-generic macro in <tgmath.h>.
- Trigonometric functions: cospi.
* The GNU C Library now supports a feature test macro _ISOC2Y_SOURCE to
enable features from the draft ISO C2Y standard. Only some features from
this draft standard are supported by the GNU C Library, and as the draft
