This is a reland of 03d5a7ba9b
Nothing changed here compared to the original test. The tests on the
blink side were invalid, I fixed them in https://crrev.com/c/2066907.
Original change's description:
> [wasm] The name of a custom section can cause a validation error
>
> The WebAssembly spec defines that the name of a custom section can cause
> a validation error. The streaming decoder, however, used a separate
> Decoder object to decode the name, and thereby avoided a validation
> error. With this CL the streaming decoder uses the main decoder to
> decode the name of the custom section.
>
> In addition this CL removes the test mjsunit/regress/wasm/regress-789952.
> This test defined an invalid WebAssembly module and expected it to
> compile. As it is a regression test, it makes no sense to fix the test.
> The module is invalid because it defines the length of the custom section
> to be '0', so there are no bytes in the custom section for its name.
