PPC/s390: [wasm] Acquire the context for TrapIf from a wasm frame

Original Commit Message:

    This is the first step to reduce the size of the out-of-line code of
    TrapIf. Instead of passing the context to the runtime call as a
    parameter, we pass Smi::kZero to the runtime call and then get the
    actual context from the WasmFrame on the stack.
