[JS IR] Materialize Unit more aggressively for IrCalls

Unit materialization for IrCall is required for operations with dynamic type.

However it produces useless Unit_getInstance() calls,
especially in return expressions. The pach also adds some heuristics
for reducing the amount of Unit_getInstance() calls from return expressions:
do not add Unit_getInstance() if return value has Unit type.
