When transforming for loop variables, the compiler does roughly
following steps:
(1) prebody = {z := z' for z in leaked}
...
(4) init' = (init : s/z/z' for z in leaked)
However, the definition of z is not updated to `z := z'` statement,
causing ReassignOracle incorrectly use the new init statement with z'
instead of z, trigger the ICE.
Fixing this by updating the correct/new definition statement for z
during the prebody initialization.
Fixes #73823
