Log Message:
-----------
Revert my best_inner_indexscan patch of yesterday, which turns out to have
had a bad side-effect: it stopped finding plans that involved BitmapAnd
combinations of indexscans using both join and non-join conditions.  Instead,
make choose_bitmap_and more aggressive about detecting redundancies between
BitmapOr subplans.
