I am still waiting for review of by auto-increment patches, and for Berndt
to complete the cross-jump part struct-equiv patches, so that I can post an
updated patch for the if-conversion part.

The patch queue also includes some patches for bugs that are not strictly speaking regressions.

Depending on how quickly that goes, and how quickly other things go,
those things may or may not make 4.2. We'll have to take it case by case.

As usual, I think we should permit the inclusion of already submitted
patches.

At this point I think it's better to wait for 4.3. I like neither of
the current proposed solutions - mine costs too much compile time, while
yours is too much of a hack. A while back I did some CSiBE testing that
did not show enough benefit for the loss of compile time. We need to
figure out something better.

Just FYI, I went through the ones that were ICE's in
add_virtual_operand, or otherwise look like aliasing, and quickly
checked whether they still cause ICE's without the whole used_alone stuff.
I've noted whether they do or not in the PR's. Hopefully this will help
someone who wants to analyze them.

This status report has been a long time coming, for which I apologize.
As fwprop is no longer on the table for 4.2, and as the vectorizer
improvements seem to have stalled due to a combination of lack of review
and Dorit's leave, I think it's time to declare 4.2 feature-complete.
That leaves us looking at regressions. There are lots; presently 56
P1s. About half of those are new in 4.2. So, we're not ready to create
a 4.2 branch.
Therefore, we need to make the mainline open for regression-fixes only
to force ourselves to attack the open bugs. Please consider the
mainline operating under release-branch rules as of 12:01 AM Wednesday,
California time. That will give everyone a few days to check in any
in-progress bug-fixes that are not regressions.
At this time, I don't think it makes sense to set a 4.2 target branch
date. We have to see how fast the bug-fixing goes.
