Description
The portions of fdlibm not already ported to Java under JDK-8134780, should be ported to Java. This remainder includes:

* sin, cos, tan
* asin, acos, atan
* sinh, cosh, tanh
* log, log10
* atan2
* expm1, log1p
Comments
Re-closing umbrella issue.

Need to backout and redo one change due to missing IEEEremainder implementation.
08-03-2023
Porting complete and C sources deleted in JDK 21; closing umbrella issue.
