    Original change's description:
    > [ignition] Add call bytecodes for undefined receiver
    > 
    > 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.
