sgemm_tcore: Support data move for fp16-packed elements
...
Since core does not support memory accesses to non-word-aligned
addresses, pack fp16 elements in pairs into fp32 values, and do regular
tile movement with conditionally compressed column dimensions.
Perf seems to stay the same for fp32 256x256.
