PPC: [builtins] Sanitize receiver patching for API functions.

Port 12bcba1543235c3e0fc02b11aecf7fc16fdf06a8

Original commit message:
    The API functions are always in sloppy mode, so receiver is always a
    JSReceiver once the actual call trampoline runs, no need to check again
    in various places.
