As was decided, I removed lowering in Autoupgrade.cpp. I also moved the tests into corresponding *target*-intrinsics-canonical.ll files as discussed with @mike.dvoretsky. I added tests for PR37260 in test/CodeGen/X86/avx2-intrinsics-canonical.ll.
What's your opinion on fast-isel subus emmision and my proposition in detectAddSubSatPattern function?
