One difference between SNB and HSW/BDW is that
number_mb_cmds(`num_macroblocks', `inline_reg0.6') is useful for SNB,
and it is UW data type,
That why I define `quality_level_ub' to be `inline_reg0.8' instead of
`inline_reg0.7`.
For HSW/BDW, num_macroblocks is useless, I define `quality_level_ub' to
be `inline_reg0.7' because I want to save reg space.
