intel/ir: Use brw::performance object instead of CFG cycle counts for codegen stats.

Browse Source 
These should be more accurate than the current cycle counts, since
among other things they consider the effect of post-scheduling passes
like the software scoreboard on TGL.  In addition it will enable us to
clean up some of the now redundant cycle-count estimation
functionality in the instruction scheduler.
