FCMify two text-based-repaint tests

FCMify two text-based-repaint tests

A previous patch (https://codereview.chromium.org/252353002) tried to
make all text-based-repaint tests use FCM, but caused flakiness reported
in http://crbug.com/367195 and http://crbug.com/367201.

It seems like the issue is that FCM wasn't being enabled soon enough. It
was turned on post-onload, after which some repaints may have been
generated. (This may no longer be true with repaint-after-layout.)

The fix is to enable FCM with the script include, rather than in
runRepaintTest.

Rather than causing churn on the entire tree, land an FCM version of
text-based-repaint.js and use it in two previous flaky tests. This
should indicate whether or not this was actually the problem.

Its it a problem that this text appears after TEXT COMPLETE?

This is a bit of awkwardness that results from combining jstest with
text-based-repaint.  The former prints out the first few messages.  The latter
prints out the repaint rects at the end.

In this particular case, maybe this test shouldn't be a repaint test.  However,
there are other more legitimate cases where a test is trying to do both.
