PPC/s390: [wasm] Stack checks should not call runtime functions but stubs

Port b0b1ba9a

Original Commit Message:

    This CL changes the secondary stack check for WebAssembly functions
    with big stack frames in the code generator from calling a runtime
    function to calling a code stub. The runtime function caused problems
    with serialization.
