  -----------
  [mlir] Fix liveness analysis for block arguments (#88848)

The current implementation does not take into account definitions
created by arguments of nested blocks. This leads to an incorrect
construction of the live-in set of an outer block. Arguments of nested
blocks are added to the live-in set of an outer block.
