Revert revisions 1383, 1384, 1391, 1398, 1401, 1402,

Revert revisions 1383, 1384, 1391, 1398, 1401, 1402,
1418, and 1419 from bleeding_edge until we have a fix
for the crashers we see on the distributed test infra-
structure.

We know that revision 1383 is causing issues, but I
had to revert some of the other recent RegExp changes
in order to get this part out.
