This reverts commit 8b89a7c32d.
Reason for revert: GC Stress tests timing out.

Original change's description:
> Update GetIterator bytecode to load and call object[Symbol.iterator]
>
> The functionality of the GetIterator bytecode introduced previously is
> now extended from loading the @@iterator property to calling the property
> as well. This change basically absorbs the functionality of additional
> two bytecodes - Star, CallProperty0 in the GetIterator bytecode.
> Importantly, this change handles the cases of eager and lazy deoptimization
> in the middle of the bytecode, i.e., lazy deopt for LdaNamedProperty and
> eager deopt of the CallProperty0 bytecode, using the continuation builtins.
> This mechanism can work as a template for the future bytecode that require
> handling such inter-bytecode deopt scenario. The tests evaluating the eager
> and lazy deopt scenarios are also included.
