func ValidatePipelineResults 

func ValidatePipelineResults(ps *v1.PipelineSpec, state PipelineRunState) error

ValidatePipelineResults ensures that any result references used by PipelineResults resolve to valid results.

	// SkipCache is a hash of PipelineTask names that stores whether a task will be
	// executed or not, because it's either not reachable via the DAG due to the pipeline
	// state, or because it was skipped due to when expressions.
	// We cache this data along the state, because it's expensive to compute, it requires
	// traversing potentially the whole graph; this way it can built incrementally, when
	// needed, via the `Skip` method in pipelinerunresolution.go
	// The skip data is sensitive to changes in the state. The ResetSkippedCache method
	// can be used to clean the cache and force re-computation when needed.
