Constant-propagate access to captured variables
* lisp/emacs-lisp/byte-opt.el (byte-optimize--substitutable-p):
Treat (internal-get-closed-var N) as constants for propagation
purposes, because that is effectively what such forms will be compiled
to. This allows for the elimination of some lexical variables.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.
