Fix command repetition with lexical-binding (Bug#29334)
`call-interactively' relies on analyzing the source of `interactive'
forms in order to preserve arguments like (region-end) in the command
history, rather than just storing the resulting position. However,
the byte-compiler does not preserve the source of the interactive form
when lexical-binding is in effect, because `call-interactively' would
evaluate the form with dynamic binding in that case.
To fix this, change `call-interactively' so that it checks compiled
functions for lexical-binding as well. Then the byte-compiler can
preserve the source of interactive forms regardless of the value of
lexical-binding.
* src/callint.c (Fcall_interactively): Functions compiled with
lexical-binding have their arglist encoded as an integer, use this to
choose the right kind of binding for compiled functions too.
* lisp/emacs-lisp/bytecomp.el (byte-compile-lambda): Preserve the
uncompiled form of the interactive form when lexical-binding is
enabled too.
