0534e5d1f6 sgemm_tcore: Fix addr gen for GMEM->SMEM for M-major A
This fixes correctness for TRANSPOSE_AT_PRODUCE/COLUMN=0/0, provided the
matrices are already stored in the correct layout in GMEM.

88cddc2b66 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.

03d1df8f53 sgemm_tcore: Separate transpose control on AS read/write
Make separate control flags on transposed AS read/write to make it easy
to model bank-conflict-free GMEM _and_ SMEM access.
