[TTI] getScalingFactorCost should return InstructionCost::getInvalid() instead of -1. (#129802)
Historically this function return an int with negative values meaning
invalid. It was migrated to InstructionCost in 43ace8b5ce07a, but the
code was not updated to return invalid cost instead of -1. In that
commit, the caller in LSR was updated to assert that the cost is valid
instead of positive. We should return invalid instead of a negative
value so LSR will assert if the cost isn't valid.
