Review comment:
`logicalPipelinedRegions` contains all regions, including the
uninitialized regions(which has uninitialized vertices). But
`executionGraphIndex.sortedExecutionVerticesInPipelinedRegion.keySet()` only
contains the initialized regions. `logicalPipelinedRegions` will cause `NPE` in
`computePipelinedRegions`
