I think this is actually a bug.  Doing `C-x b' with non-nil
display-buffer-reuse-frames should make Emacs raise another frame if
it;s already displaying the desired buffer---regardless of the value of
pop-up-frames.

Currently, if display-buffer-reuse-frames and pop-up-frames are both t,
`C-x b' instead displays the buffer in the existing frame.  So
`pop-up-frames' has changed the behavior, even though it's not doing any
"popping up" in this case.
