glsl/builtin: Add alternate versions of atan using new ops
Adds alternate versions of the atan builtin functions that use ir_unop_atan and ir_binop_atan2 instead of inlining to the IR implementation of the function. These alternatives are selected if the IR is going to be consumed by NIR. In that case the IR ops will be translated to the appropriate NIR op. Reviewed-by: Kristian H. Kristensen <hoegsberg@google.com>
