Compile cond with heterogeneous tests into switch (bug#36139)
Allow any mixture of `eq', `eql' and `equal', `memq', `memql' and
`member' in a switch-like `cond' to be compiled into a single switch.
* lisp/emacs-lisp/bytecomp.el (byte-compile--common-test): New.
(byte-compile-cond-jump-table-info): Use most specific common test.
* test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data):
Add test cases for multi-value clause cond forms.
