Issue: #<!-- -->70096
Changes:
- Doc updates:
- `clang/docs/LanguageExtensions.rst` - Document the new elementwise atan2 builtin.
- `llvm/docs/LangRef.rst` - Document the atan2 intrinsic
- TableGen:
- `clang/include/clang/Basic/Builtins.td` - Implement the atan2 builtin.
- `llvm/include/llvm/IR/Intrinsics.td` - Create the atan2 intrinsic
- Sema checking:
- `clang/lib/Sema/SemaChecking.cpp` - Add generic sema checks to the atan2 builtin
- `clang/lib/Sema/SemaHLSL` Add HLSL specifc sema checks to the atan2 builtin
- `clang/lib/CodeGen/CGBuiltin.cpp` - invoke the atan2 intrinsic on uses of the builtin
- `clang/lib/Headers/hlsl/hlsl_intrinsics.h` - Associate the atan2 builtin with the equivalent hlsl apis
This change is an implementation of #<!-- -->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

+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Syntax:

+
+This is an overloaded intrinsic. You can use ``llvm.atan2`` on any

+
+Overview:
+"""""""""
+
+The '``llvm.atan2.*``' intrinsics return the arctangent of the operand.
+
+Arguments:
+""""""""""
+
+The arguments and return value are floating-point numbers of the same type.
+
+Semantics:
+""""""""""
+
+Return the same value as a corresponding libm '``atan2``' function but without
+trapping or setting ``errno``.
