I'd start with:

(progn
  (goto-char (window-end))
  (forward-line -1))

and work round problems like partial lines, the last line not having a
newline after it and whether the display changes as a result of the
positioning as you encounter them!

Caveat: I'm no expert.  For all I know there's a
"put-point-at-start-of-last-whole-visible-line-in-window-without-scrolling"
function.
