PPC/s390: [builtins] Add receiver to builtin exit frames

PPC/s390: [builtins] Add receiver to builtin exit frames

Port f59a23356b437e369d75445177fea838ee5bccc7

Original commit message:

    Stack trace generation requires access to the receiver; and while the
    receiver is already on the stack, we cannot determine its position
    during stack trace generation (it's stored in argv[0], and argc is only
    stored in a callee-saved register).

    This patch grants access to the receiver by pushing argc onto builtin
    exit frames as an extra argument. Compared to simply pushing the
    receiver, this requires an additional dereference during stack trace
    generation, but one fewer during builtin calls.
