bounded pointers progress report

[Greg McGary]

As of last night, I have implemented full checks for ix86 with
optimization of redundant checks.  I can build GNU libc 2.1 (at the
head of glibc-2-1-branch updated from CVS last night), and most of
GNU textutils & fileutils.  I haven't tried them all, but many work.
I even found a bounds-violation bug in GNU pr.

Things are far enough along that it would be useful to make this
available for others to test & debug.

Since turnaround for review of patches is slow, I fear it might take
months to get it all checked into the gcc mainline.  What's the
possibility of starting a CVS branch for bounds checking?  If a branch
isn't possible, then I suppose I could publish patches against
the weekly snapshots.

Please advise.
