Original issue's description:
> PPC/s390: [ignition] Add call bytecodes for undefined receiver
>
> Port 751e89359123df4f6e5f0b28b89fcdf63ed16a77
>
> Original Commit Message:
>
> Adds a collection of call bytecodes which have an implicit undefined
> receiver argument, for cases such as global calls where we know that the
> receiver has to be undefined. This way we can skip an LdaUndefined,
> decrease bytecode register pressure, and set a more accurate
> ConvertReceiverMode on the interpreter and TurboFan call.
>
> As a side effect, the "normal" Call bytecode now becomes a rare case
> (only with calls and super property calls), so we get rid of its 0-2
> argument special cases and modify CallProperty[N] to use the
> NotNullOrUndefined ConvertReceiverMode.
