    [wasm] Introduce dependency of JS/Wasm frame in wasm-compiler · 06212c9a
    Manos Koukoutos authored
    In wasm-compiler, nodes that reference the Isolate and Instance should
    depend on whether the current frame JS or Wasm. This was implemented
    with mutable fields caching nodes in WasmGraphBuilder and its
    subclasses, but was not done consistently.
    This CL removes all mutability and replaces it with an additional field
    isolate_ in WasmGraphBuilder, which is only set in the constructor of
    the child class WasmWrapperGraphBuilder.
    
    Additional changes:
    - Remove three almost-unused utilities from WasmGraphAssembler.
    - Reduce duplicate BuildImportCall with int index argument to the one
      with Node* index argument (the additional operations should be
      optimized away).
