[RenderScript] New command for viewing coordinate of current kernel invocation

Patch adds command 'language renderscript kernel coordinate' for printing the kernel index in (x,y,z) format.
This is done by walking the call stack and looking for a function with suffix '.expand', as well as the frame variables containing the coordinate data.
