Add more JS subtyping semantics to CFE constant evaluator.

If we're targeting a JS backend, `isSubtype` considers every int to be a
double. We need to additionally allow any integer-valued double to be an
int. This mainly allows us to handle signed zeroes correctly.

Fixes https://github.com/dart-lang/sdk/issues/36562.
