PPC/s390: [builtins] Introduce a builtin for Abort().

Port 9be015a2

Original commit message:

    Calling Runtime::kAbort through a builtin instead of the c-entry stub
    will allow to generate the call in a background thread, because a
    builtin provides its own handle, whereas a code stub does not.
