I took the function 'note_mouse_highlight' from xdisp.c, pushed all
lines to column 0 and ran:

Keep in mind that the indentation result is not 100% identical, but I
doubt that will change anything. I'll benchmark everything again when
we're satisfied with the behavior.  This is only 2 evenings worth of
hacking.

(defun xdisp-indent-benchmark (mode)
  (benchmark-run 10
    (progn
      (with-current-buffer (find-file "~/src/tree-sitter-modes/xdispfun.c")
        (funcall mode)
	      (mark-whole-buffer)
        (indent-for-tab-command)
        (undo))
      (kill-buffer "xdispfun.c"))))
