c4938ea2ba Tie up the loose ends in the ExprList size reduction.

cbb9da337e Work toward reducing the incremental size of an ExprList object to 24-byte 
per entry, from 32-bytes (on a 64-bit machine).  This helps the new
mini-lookaside allocator to run better by avoiding excessive reallocs.
The current change mostly works, but still has a few loose ends to tie up.
This check-in is merely a snapshot to save my work.
