…st` (#152410)

Closes #51135.
Closes #145499.

Making this the _default_, or better discoverable, is tracked in
#152409.

You'll notice I also removed `-rexpanded`; @jonahwilliams believes that
was accidentally copied over from else-where, and never did anything
(someone I guess could have parsed it in `void main(...)`, but given
#51135 &
#145499 that seems unlikely.
