  Log Message:
  -----------
  [mlir][bufferization] Better analysis around allocs and block arguments (#67923)

Values that are the result of buffer allocation ops are guaranteed to
*not* be the same allocation as block arguments of containing blocks.
This fact can be used to allow for more aggressive simplification of
`bufferization.dealloc` ops.
