This PR changes the compiler's specialization analysis to consider higher-order params that are rebundled in a way that only changes their `Prop` arguments to be fixed. This means that they get specialized with a mere `@[specialize]`, rather than the compiler having to opt-in to more aggressive parameter-specific specialization.
