I raised similar thoughts in a [previous comment](https://github.com/llvm/llvm-project/pull/89982#discussion_r1581533949). 
Is it valid to use the `__math/` folder instead of a newly created `__cmath/` folder? Note, that the special math functions are only part of the `<cmath>` and not `<math.h>` header. 
In general, I am more than in favor to move that code into a separate header.
