profiling of concat op (both cuda and cpu) (#151)
* - profiling of concat op (both cuda and cpu) Signed-off-by: Yurii <iuriish@yahoo.com> * better comparison for large concat Signed-off-by: raver119 <raver119@gmail.com> * - further improving of concat op Signed-off-by: Yurii <iuriish@yahoo.com> * some loggin Signed-off-by: raver119 <raver119@gmail.com> * - add possibility to verify presence of trailing unities in shape and set strides/ews correspondingly - restrict second simple case in concat op to c order only Signed-off-by: Yurii <iuriish@yahoo.com> * - move concat op to specials_single.cpp file Signed-off-by: Yurii <iuriish@yahoo.com> * - get rid of second concat op declaration in transforms.cpp file Signed-off-by: Yurii <iuriish@yahoo.com> Co-authored-by: raver119 <raver119@gmail.com>master
