  -----------
  [mlir][SCF]-Fix loop coalescing with iteration arguements (#105488)

Fix a bug found when coalescing loops which have iteration arguments,
such that the inner loop's terminator may have operands of the inner
loop iteration arguments which are about to be replaced by the outer
loop's iteration arguments.

The current flow leads to crush within the IR code.
