  [NFC][SCEV] `computeSCEVAtScope()`: deduplicate handling

Casts and udiv get the exactly the same handling as n-ary,
there is no point in special-handling anything.

  -----------
  [NFC][SCEVExpander] `CmpSelCost`: use the cost of the expression, not operand

Currently, for all invocations, it's equivalent, since that is literally
how `SCEVMinMaxExpr::getType()` is defined. But for e.g. `select`,
we'll want to ask about the hand type, and not the type of the operand
that happens to be first.
