Cuong Manh Le a0dc7bf084 cmd/compile: fix ICE when transforming loopvar
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
