sgemm_tcore: Hardcode threadblock id 0
...
this is fine since we're statically dispatching only one threadblock to
the whole cluster.

sgemm_tcore: Bring M/N-loop inside the kernel
...
Instead of spawning multiple threadblocks which comes with stack access
overhead, have 1 threadblock work on the entire M/N-space thru a loop.
Grid size is fixed to the hardware parallelism.
TODO currently only works with 1 cluster in the system.
