Stage half-operands per warp
...
An easy solution to handle multiple concurrent warp operations by
staging half-operands in their own per-warp register. This might
increase area requirement by quite a bit.

tensor: Add buffer to hide 2cyc commit latency
...
Since operand and commit throughput are the same (2 cycles), it is
unnecessary to stall the dpu during the multi-cycle commit.
This enables the dpu to operate at full throughput of 1 operand every 2
cycles.
