Summary: X-link: facebookresearch/FBGEMM#475 Instead of over launching thread blocks, use `b_t_map` to launch only necessary thread blocks to increase occupancy for the VBE case Note that `b_t_map` is necessary for the TBE look for the VBE case. It is generated during the TBE forward pass. In this diff, we call `generate_vbe_metdata` twice (before bounds check and before forward look up). These two calls can be fused into one. We will clean this up in the subsequent diffs. Differential Revision: D65735342

Instead of over launching thread blocks, use
b_t_mapto launch onlynecessary thread blocks to increase occupancy for the VBE case
Note that
b_t_mapis necessary for the TBE look for the VBE case. Itis generated during the TBE forward pass. In this diff, we call
generate_vbe_metdatatwice (before bounds check and before forwardlook up). These two calls can be fused into one. We will clean this
up in the subsequent diffs.
