[x265] [Patch] fix: corrects output mismatch for cutree enabled analysis save/load enodes with reuse-levels in between 1 to 10 for similar encoder settings.

[AM] Can't we share lowres cutree stats generated at qg size granularity?
Why MAX_NUM_CU_GEOMS combinations?

[KS] If we share like that then we will have to calculate the dqp per cu at
analysis phase just like save encode and we will not get the savings in cpu
cycles there. Currently we are storing the final dqp derived from lowres mv
costs at qg size granularity by taking the difference between the final qp
and base qp per slice.

MAX_NUM_CU_GEOMS is 85 = ( 1 + 4 + 16 + 64 ) this is maximum number of
partitions at which qp can be computed and used in a ctu.

[AM] Won't this implicitly turn OFF cutree at reuse-level 1?

[KS]  Agreed and addressed.
