This patch changes the type of BudgetRemaining and Cost in
costAndCollectOperands from 'unsigned' to 'InstructionCost' so that it
can take into account an Invalid cost. isHighCostExpansion will return
true if the cost is invalid, but the patch is NFC until any of the cost
functions return a Invalid cost.
