It appears that storage for varyings in a wave has an upper
limit of wavesize * max_a831 where max_a831 is 64.
Exceeding the limit seam to force gpu to reduce primitives
processed per wave, at least calculations make sense with
such interpretation.
With blob SP_HS_WAVE_INPUT_SIZE never exceeds 64 and setting
it to 65 in freedreno leads to a hang.
