* cl-macs.el (cl--transform-lambda): Refine last change.

Fixes: debbugs:20125

* test/automated/cl-lib-tests.el: Use lexical-binding.
(cl-lib-arglist-performance): Refine test to the case where one of the
fields has a non-nil default value.  Use existing `mystruct' defstruct.
(cl-lib-struct-accessors): Use `pcase' to be a bit more flexible in the
accepted outputs.
