Alexander Alekhin ef5fa498d4 [move sift.cpp] sift: perf tests and trace regions 
original commit: https://github.com/opencv/opencv_contrib/commit/a15e105db12aa7a0bade47afb791682201e46f60

ab-dragon 2947877871 [move sift.cpp] Merge pull request opencv/opencv_contrib#2301 from ab-dragon:conditionally_compute_dog_pyramid 
Build DoG Pyramid if useProvideKeypoints is false

The buildDoGPyramid operation need not be performed unconditionally. In cases where it is not needed, both memory and speed performance can be improved
