force-load-messages is nil by default, and currently isn't used at all
by Emacs.  It seems to be a pure debugging variable.

The NOMESSAGE argument to Fload when non-nil, causes the unwanted
message:

    Source file `foo.el' newer than byte-compiled file; using older file

..  When NOMESSAGE is nil, we get instead

    Loading foo.elc (compiled; note, source file is newer)...

..  Whichever setting of NOMESSAGE and force-load-messages we use, we get
one of the above messages displayed.  So, I'm proposing using a new
value 'never for force-load-messages to mean display neither of these
messages.
