This change is 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 constraint intrinsics and some lowering cases for `acos`, `asin`, `atan`, `cosh`, `sinh`, and `tanh`. The only x86 specific change was for f80. https://github.com/llvm/llvm-project/issues/70079 https://github.com/llvm/llvm-project/issues/70080 https://github.com/llvm/llvm-project/issues/70081 https://github.com/llvm/llvm-project/issues/70083 https://github.com/llvm/llvm-project/issues/70084 https://github.com/llvm/llvm-project/issues/95966 The x86 lowering is going to be done in three pr changes with this being the first. A second PR will be put up for Loop Vectorizing and then SLPVectorizer. The constraint intrinsics is also going to be in multiple parts, but just 2. This part covers just the llvm specific changes, part2 will cover clang specifc changes and legalization for backends than have special legalization requirements like aarch64 and wasm.
