Don't create *Compile-Log* due to byte-compile. Amend message to it.

This fixes bug #33602 and is a partial reversion of a commit from
2018-11-28T13:15:50.

* lisp/emacs-lisp/bytecomp.el (byte-compile-log-file): Don't create buffer
*Compile-Log* because it doesn't already exist.  Amend message "Compiling no
file" to be clearer (?and less irritating).
