    [wasm] Delay error messages for lazy compilation · fe53fbfc
    Andreas Haas authored
    With streaming compilation we delay the generation of errors until after
    all bytes are received, so that potentially better error messages get
    generated. With this CL we also delay the generation of errors in the
    combination of lazy compilation and streaming compilation.
    
    In particular, this CL does the following:
    * It avoids the creation of a `DecodeFail` task in
    `FinishAsyncCompileJobWithError`, which would create an error immediately before a potential name section arrived.
    * It calls `CompilationStateImpl::SetError()` so that an error is
    created once the stream finishes.
    * It removes the return value of `ProcessFunctionBody` so that wire
    bytes continue to be received even after a validation error.
    * It adds an early exit to `ProcessFunctionBody` if
    `CompilationStateImpl::failed()` is true, so that we don't continue
    validation after the first detected error.
