Hans Wennborg 67c03759e4 Switch lowering: Take branch weight into account when ordering for fall-through ...

Previously, the code would try to put a fall-through case last,
even if that meant moving a case with much higher branch weight
further down the chain.

Ordering by branch weight is most important, putting a fall-through
block last is secondary.
