runtime(syntax-tests): Apply stronger synchronisation between buffers
The current lightweight synchronisation with ":redraw" needs further
reinforcement in the light of v9.1.1110. And, with v9.1.0820, make
another synchronisation point _before_ the first (or only) screenful is
dumped.
Also add a script to regenerate all screendumps.
