Mattias Engdegård 537f78b537 Warn about unmatchable constant args to eq, memq etc 
Add a byte-compiler warning about attempts to compare literal values
with undefined identity relation to other values.  For example:

  (eq x 2.0)
  (memq x '("a" (b) [c]))

Such incomparable values include all literal conses, strings, vectors,
records and (except for eql and memql) floats and bignums.
The warning currently applies to eq, eql, memq, memql, assq, rassq,
remq and delq.

* lisp/emacs-lisp/bytecomp.el (bytecomp--dodgy-eq-arg)
(bytecomp--value-type-description, bytecomp--arg-type-description)
(bytecomp--warn-dodgy-eq-arg, bytecomp--check-eq-args)
(bytecomp--check-memq-args): New.
(eq, eql, memq, memql, assq, rassq, remq, delq):
Set compiler-macro property.
* lisp/emacs-lisp/byte-run.el (with-suppressed-warnings):
Amend doc string.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp--with-warning-test): Fix text-quoting-style and expand
re-warning so that it doesn't need to be a literal.
(bytecomp-warn-dodgy-args-eq, bytecomp-warn-dodgy-args-memq):
New tests.
