[code-reflection] RFR: [hat][api] Number of blocks introduced with kernelContext.bs[xyz] [v2]

[Juan Fumero]

> Number of blocks introduced with kernelContext.bs[xyz].

> This construct allows us to obtain the number of blocks use within the kernel code:

> For example:

> 
> int numBlocks = kernelContext.bsx;
> 
> 
> How to test?
> 
> 
> # OpenCL 
> HAT=SHOW_CODE java -cp hat/job.jar hat.java test ffi-opencl hat.test.TestNumBlocks
> # CUDA
> HAT=SHOW_CODE java -cp hat/job.jar hat.java test ffi-cuda hat.test.TestNumBlocks
