Alexander Smorkalov ab006c9201 Merge pull request #3081 from asmorkalov:as/stereo_bm_uniqueness_ratio
Uniqueness ratio support for cuda::StereoBM

* Naive implementation of uniqueness ratio option for cuda::StereoBM.

* Optimized memory consumption in cuda::stereoBM with uniqueness check.

* Got rid of line_disps array.

* Reduced line_ssds.

* Apply streams for all parts of cuda::stereoBM::compute.

* Added perf test for CUDA stereoBM with uniqueness check.

* Optimized global memory transactions.

* Restored sync data transfers as they use stack variables.

* Do not use constant memory in stereoBM to exclude stream races.

* Code review fixes.
