The order pass ensures that initialization operations for clear(expr) are scheduled. However, if 'expr' is a conversion that the walk pass subsequently optimizes away or transforms, the resulting nodes can be left in an un-walked state. These un-walked nodes reach the SSA backend, which does not expect high-level IR, resulting in an ICE. This change ensures the expression is always walked during the transformation of the 'clear' builtin.
