Stefan Monnier b41b4add7b Fix spurious "Lexical argument shadows the dynamic variable" due to inlining
Before this patch doing:

    rm lisp/calendar/calendar.elc
    make lisp/calendar/cal-hebrew.elc

would spew out lots of spurious such warnings about a `date` argument,
pointing to code which has no `date` argument in sight.  This was
because that code had calls to inlinable functions (taking a `date`
argument) defined in `calendar.el`, and while `date` is a normal
lexical var at the site of those functions' definitions, it was
declared as dynbound at the call site.

* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand):
Don't impose our local context onto the inlined function.

* test/lisp/emacs-lisp/bytecomp-tests.el: Add matching test.

;; inlinable function from another file where `foo-var' is a normal
;; lexical variable, and then call(inline) it in a function where
;; `foo-var' is a dynamically-scoped variable.
