This helps to reduce peak memory in lowerings/codegen by a lot. A more robust approach would be to have a separate BindingContext for each file, and clear each of them after running psi2ir on it. This would also lower peak memory usage in psi2ir. Provide a fallback workaround compiler argument -Xir-do-not-clear-binding-context just in case BindingContext is in fact used somewhere and it's not caught by tests.
