Further speedups of redisplay of long and truncated lines
* src/xdisp.c (mode_line_update_needed, redisplay_window)
(decode_mode_spec): Don't avoid calling current_column, as it is
now fast enough.
(redisplay_window) <optional_new_start>: Don't call 'move_it_to'
if its result will not be used.
(Flong_line_optimizations_p): New primitive.
* src/indent.c (Fcurrent_column): Doc fix.
(current_column, scan_for_column): When in a buffer with long
and/or truncated lines, quickly return an approximate value.
* src/window.c (Frecenter): Use the old text-mode code when the
buffer has very long lines.
* lisp/simple.el (line-move): Avoid costly calls to
'line-move-partial' and 'line-move-visual' when lines are
truncated and/or very long.
(move-beginning-of-line): Call 'line-beginning-position' instead
of the slower 'skip-chars-backward'.
* etc/NEWS: Announce 'long-line-optimizations-p'.

I will look at the changes in simple.el soon if no-one beats me.
