tz: optimize AVX2 implementation
...
1. Perform masking with 2 instructions instead of 3 (use arithmetic
shift).
2. Broadcast data byte in one instruction at the start of byte-processing
3. Reorder instructions to reduce the amount of data hazards and resources
contention.

We use 6 instructions only to calculate mask based on single bit value.
Use only 3 now and calculate multiple masks in parallel.
Also `VPSUB*` is faster than VPBROADCAST*,
