When working on an OpenMP offloading backend for standard parallel algorithms (https://github.com/llvm/llvm-project/pull/66968) we noticed the need of a generalization of `__is_trivial_plus_operation`. This patch merges `__is_trivial_equality_predicate` and `__is_trivial_plus_operation` into `__desugars_to`, and in the future we might extend the latter to support other binary operations as well.
