PPC/s390: [stubs] Port CreateWeakCellStub to turbofan

Port 7f1fa30e3437d38ab7c949c19659f52e8233fba9

Original commit message:

    In the process also inline the stub into the appropriate interpreter bytecode
    handler and make sure that the context register is preserved in hand-written
    assembly code that calls the stub and expects the context register to be
    preserved.
