Build failure about ext HOT 1 CLOSED

I borrowed this from WebKit, but it looks like I might need to rework a few things.

Here are the same lines from WebKit: https://github.com/WebKit/WebKit/blob/6d13b1672d0f7ce5a6f8093e1ed597e0bd0f2cf2/Source/JavaScriptCore/runtime/IntlObject.cpp#L1148-L1152

VariantCode is a uint64_t, while Code is:

  struct Code {
    std::array<LChar, 8> characters{};
  };

And LChar is unsigned char.

I think what's happening here is largely a result of my lack of understanding about that assertion. Maybe WebKit wants to force use of a specific set of compilers where these values would have the same size?

Should I remove the assertions and rely on the compilers to do the right thing, or should I change the data types here to be less specific? Maybe just use uint instead?
