When evaluate-in-inferior-repl is true, distinguish between

When evaluate-in-inferior-repl is true, distinguish between
evaluations done in inferior REPL buffers and evaluations done in
other buffers (and the minibuffer); change the latter so that the
value of the evaluation is printed in the minibuffer, just as it would
have been if evaluate-in-inferior-repl were false.  Furthermore, if
there is no inferior REPL, M-x eval-expression now works anyway.
