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
