Actually I don't think I can prove that the LAP code will never have the pattern that triggered the bug in Emacs 29; nothing prevents it in principle from occurring anyway.

It doesn't seem safe to keep the buggy limplification in that branch -- I suggest we remove the switch-eliminating optimisation in comp.el altogether just in case. What do you think?
