    [wasm] Fix/restrict large-function TF bailout · 5af79486
    Jakob Kummerow authored
    This CL addresses two problems:
    - the previous implementation of the large-function TF bailout
      didn't work for streaming compilation, because it tried to look
      at the size of wire bytes that weren't yet available. Moving the
      logic so it gets executed later ensures that the function size
      is available.
    - module serialization currently requires all functions to be
      compiled with Turbofan, so the hard limit breaks serialization for
      modules containing such huge functions. This CL enables the limit
      only for --experimental-wasm-gc, so that non-experimental modules
      continue to be serializable as they always have been. In the
      future, we will avoid this limitation by making serialization more
      flexible.
