[CostModel][Test] Replace multiple flags with -intrinsic-cost-strategy

This replaces the `-prefer-intrinsic-cost` and `type-based-intrinsic-cost`
flags with a single `-intrinsic-cost-strategy=<strategy>` flag.

The possible strategies are:

 * `instruction-cost`
   - Use TargetTransformInfo::getInstructionCost()
 * `intrinsic-cost`
   - Use TargetTransformInfo::getIntrinsicInstrCost()
 * `type-based-intrinsic-cost`
   - Calculate intrinsics cost based only on argument types
