Title: Make haxe.Int64 into an abstract

This allows Ints and Floats to automatically be cast to Int64, and
allows for the use of operators (+, -, >>, etc.)

I moved what was formally at haxe.Int64 to haxe.Int64Data. I would have liked to keep it within Int64, but I'm not sure how that would work with the files in _std.
