Matthew Flatt 23f6d1a651 optimizer: reorganize & generalize dropping of ignored operations
The optimizer was willing to convert `(pair? (cons w (random)))` to
`(begin (random) #t)`, but not `(car (cons w (random)))` to
`(begin (random) w)` because the `(car (cons ....))` transformation
required simple ignored arguments. Put the treatment of ignored,
non-omittable arguments of a dropped operation in one place. Also,
recognize expressions within `begin` whose results will be ignored.
