I've now pushed the 0001 patch to cache the volatility of PathTarget
and RestrictInfo.
I'll be looking at the remaining patches over the next few days.
Attached are a rebased set of patches on top of current master. The
only change is to the 0003 patch (was 0004) which had an unstable
regression test for parallel plan with a Result Cache. I've swapped
the unstable test for something that shouldn't fail randomly depending
on if a parallel worker did any work or not.
