  [clang] Emit constraint intrinsics for arc and hyperbolic trig clang builtins (#98949)

## Change(s)
- `Builtins.td` - Add f16 support for libm arc and hyperbolic trig
functions
- `CGBuiltin.cpp` - Emit constraint intrinsics for trig clang builtins

## History
This change is part of an implementation of
https://github.com/llvm/llvm-project/issues/87367's investigation on
supporting IEEE math operations as intrinsics. Which was discussed in
this RFC:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294

This change adds wasm lowering cases for `acos`, `asin`, `atan`, `cosh`,
`sinh`, and `tanh`.
