  -----------
  [mlir][IR] Add `Block::isReachable` helper function (#114928)

Add a new helper function `isReachable` to `Block`. This function
traverses all successors of a block to determine if another block is
reachable from the current block.

This functionality has been reimplemented in multiple places in MLIR.
Possibly additional copies in downstream projects. Therefore, moving it
to a common place.
