Log message:
        Lexical binding support (not finished yet):
        
        Require `macroexp'.
        (byte-compile-lexical-environment)
        (byte-compile-current-heap-environment)
        (byte-compile-current-num-closures): New variables.
        (0, 178, 179, 180, 181): New byte-opcodes.
        (byte-compile-lapcode): Handle stack-ref/set opcodes.  Signal an
        error if a delay-output placeholder is not filled in yet.
        (byte-compile-file-form, byte-compile): Expand all macros with
        `macroexpand-all'.
        (byte-compile-file-form-defsubst, byte-compile-form): Don't expand
        macros here.
        (byte-compile-make-lambda-lexenv): Autoload.
        (byte-compile-lambda): Initial code for handling lexically-bound
        arguments and closures; doesn't work yet.
        (byte-compile-closure-code-p, byte-compile-make-closure)
        (byte-compile-closure): New functions.
        (byte-compile-check-variable, byte-compile-dynamic-variable-op)
        (byte-compile-dynamic-variable-bind)
        (byte-compile-lexical-variable-ref, byte-compile-variable-set):
        New functions.
        (byte-compile-variable-ref): Remove second argument.  Now only
        handles real variable references (not setting or binding).
        (byte-compile-push-unknown-constant)
        (byte-compile-resolve-unknown-constant): New functions.
        (byte-compile-funarg, byte-compile-funarg-2): Functions removed.
        (byte-compile-function-form): Use either `byte-compile-constant'
        or `byte-compile-closure'.
        (byte-compile-setq): Use `byte-compile-variable-set' instead of
        `byte-compile-variable-ref'.
        (apply, mapcar, mapatoms, mapconcat, mapc, sort):
        `byte-defop-compiler-1's removed.
        (byte-compile-while): Make sure lexically-bound variables inside
        the loop don't get stored in an environment outside the loop.
        (byte-compile-compute-lforminfo): Autoload.
        (byte-compile-push-binding-init): New function.
        (byte-compile-let, byte-compile-let*): Handle lexical binding.
        (byte-compile-defun): Use `byte-compile-closure' to do the work.
        (byte-compile-defmacro): Use `byte-compile-make-closure'.
        (byte-compile-defvar): Expand the generated call to `push' since
        we're past macroexpansion already.
        (byte-compile-stack-adjustment): New function.
        (byte-compile-out): Make second arg optional.  Rewrite for clarity.
        (byte-compile-delay-out, byte-compile-delayed-out): New functions.
