Late in the development of commit 0dca5d68d, I added a step to copy the result tlist we extract from the cached final query, because I was afraid that that might not last as long as the JunkFilter that we're passing it off to. However, that turns out to cost a noticeable number of cycles, and it's really quite unnecessary because the JunkFilter will not examine that tlist after it's been created. (ExecFindJunkAttribute would use it, but we don't use that function on this JunkFilter.) Hence, remove the copy step. For safety, reset the might-become-dangling jf_targetList pointer to NIL. In passing, remove DR_sqlfunction.cxt, which we don't use anymore; it's confusing because it's not entirely clear which context it ought to point at.
