Original issue's description:
> Added support for Time Elapsed queries through the command buffer.
>
> This CL adds support for Time Elapsed queries through the command
> buffer.
>
> Since it was easy to support, I have also added support
> for getting the current TimeStamp through GetInteger64(),
> GetInteger()...etc. Note that this is different from getting the
> GPU timestamp using QueryCounter which is asynchronous.
