As required by the spec, ToJS now throws a TypeError fit I64 values instead of truncating the I64 value to I32. To throw a TypeError I introduced a new runtime function because the existing Runtime::kThrowWasmError does not throw a TypeError. Since we have calls to two runtime functions now, and an additional one is needed for stack checks, I extracted the call to runtime functions into a helper function.
