Jaroslav Sevcik 60c0edc08c [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").
