[WebAssembly] Add Support for Arc and Hyperbolic trig llvm intrinsics…
Browse files Browse the repository at this point in the history 
… (#98755)

## Change:
- WebAssemblyRuntimeLibcallSignatures.cpp: Expose the RTLIB's for use by
WASM
-  Add trig specific test cases

## History
This change is part of an implementation of
llvm/llvm-project#87367 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`.

llvm/llvm-project#70080
llvm/llvm-project#70081
llvm/llvm-project#70083
llvm/llvm-project#70084
llvm/llvm-project#95966

## Why Web Assembly?
From past changes to try and support constraint intrinsics the changes
to the trig builtins to emit intrinsics\constraint intrinsics broke the
WASM build. This is an attempt to preempt any such build break.
