[interpreter] Store CreateObjectLiteral's result into the accumulator. As opposed to the register. For subtle reasons, this fixes a deoptimizer bug with handling return values in lazy deopt. Since the return values can now only overwrite the accumulator, there is no danger of overwriting a captured object that might be later used (since there is no "later").

This CL avoids allocating CallICslots for each function call by emitting CallNoFeedback bytecodes. We save one CallICSlot (two entries in feedback vector) per function call in One-shot.
