• [x] support warp reuse mode for loading operand A in gemm
• [x] support warp reuse mode for loading operand B in gemm
• [x] test on the gemm example.

Since the store from register to shared memory is not yet complete, a unit test to ensure correctness is not included in this PR. This will be added later.
