Implement C23 rsqrt 

C23 adds various <math.h> function families originally defined in TS
18661-4.  Add the rsqrt functions (1/sqrt(x)).  The test inputs are
taken from those for sqrt.

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

Major new features:
[Add new features here]
* 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>.
- Power and absolute-value functions: rsqrt.
Deprecated and removed features, and other changes affecting compatibility:
