Make use of statistics on index expressions.  There are still some
corner cases that could stand improvement, but it does all the basic
stuff.  A byproduct is that the selectivity routines are no longer
constrained to working on simple Vars; we might in future be able to
improve the behavior for subexpressions that don't match indexes.
