1182	Bug in spec for affine AMVP list construction	chhuanb		"In clause ""8.5.5.7 Derivation process for luma affine control point motion vector predictors"", step 6, affine constructed candidate is inserted into candidate list when availableConsFlagLX is equal to 1, and '''numCpMvpCandLX is equal to 0'''.
The second condition is not present in the SW and the SW matches the original design for affine AMVP list construction.

Suggest spec fixes:

6.	When numCpMvpCandLX is less than 2, the following applies
–	The derivation process for constructed affine control point motion vector prediction candidate as specified in clause 8.5.5.8 is invoked with the luma coding block location ( xCb, yCb ), the luma coding block width cbWidth, the luma coding block height cbHeight, and the reference index of the current coding unit refIdxLX as inputs, and the availability flag availableConsFlagLX, the availability flags availableFlagLX[ cpIdx ] and cpMvpLX[ cpIdx ] with cpIdx = 0..numCpMv − 1 as outputs.
–	When availableConsFlagLX is equal to 1, ~~and numCpMvpCandLX is equal to 0,~~ the following assignments are made:
