cmd/compile: ensure map/slice clearing expressions are walked
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.
Fixes #78410
