fix bug in seq rewriter op_cache::find (#4509) 
* remove unneeded reverse case in derivative; placeholder for generalized lifted derivative

* experimental tweaks to RE rewriter to improve performance

* if-then-else lifting
(broken code -- preserving this commit in case this idea is useful later)

* if-then-else derivative optimizations: new approach templates

* implement if-then-else BDD normal form for derivatives
(code compiles but is still buggy)

* remove std::cout debugging for PR

* Revert "remove std::cout debugging for PR"

This reverts commit c7bdc44d31.

* debugging

* fix derivative interaction with reverse; add flags for left/right derivative and lifting over union/intersection

* remove debugging statements for PR

* Revert "remove debugging statements for PR"

This reverts commit 38e85a7288.

* revert some purely cosmetic changes from upstream; fix a bug

* revert unnecessary changes

* remove some redundant rewrites and add a new one for str.in_re(s, comp(r))

* add disabled rewrite for complement

* fix bug in op cache find (result was not saved)

* remove debugging std::cout for PR
