           Summary: JSONValue of signed and unsigned equal values is not

Repro:

assert(JSONValue([].length) == JSONValue(0));

JSONValue treats them as two different types because one is signed and one is
unsigned. Which is of course nonsense and against spec. JSON doesn't even have
unsigned types; strictly speaking you're supposed to just use doubles for ints,
like JS does. But if there have to be integers in JSONValue, they should work
with doubles, and they *certainly* should work with *themselves*.
