Linearization does not apply to chained LIR evaluation

OVM -lin works if chained with -show-ast. However, it does not work with a chained -lir, which runs LIR evaluation.

For instance, ovm -lin -lir treetests/15.hir results in an error caused by non-linearized IR. Linearization is not taken intop account during the evaluation.
