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.

This is actually quite annoying and kinda dramatic and it is not something we
*need* to do right away, but I'd like to get the known crasher (likely
introduced in 1383) out of the bleeding_edge branch soon to make it possible to
start testing the new compiler that landed on bleeding_edge in revision 1389.

Please advice on how you want to proceed.

LGTM

If we cannot find the issue with revision 1389 today or tomorrow, I think we
need to do this so we can do some stress testing of the new compiler.
