Tighter pcase or-pattern member function selection (bug#36139)
* lisp/emacs-lisp/pcase.el (pcase--u1):
Use the most specific of `memq', `memql' and `member' in or-patterns
with constant cases. This improves performance and may help the byte-code
compiler generate a switch.
* test/lisp/emacs-lisp/pcase-tests.el (pcase-tests-member):
Add mixed-type or-pattern test cases.
