Fix condition-case body for-effect miscompilation

(condition-case x A (:success B)) should not compile A for-effect even
if the entire form is in for-effect context.

* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Don't optimise the condition-case body form for effect (potentially
discarding its value) if there is a success handler and a variable.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test cases.
