Yes, and the code at 1548 in AutoUpgrade.cpp does that. There are existing tests in avx512bw-intrinsics-upgrade.ll and avx512bwvl-intrinsics-upgrade.ll that were previously testing upgrade from old intrinsics to pure IR that now just test old intrinsics to new intrinsics. The codegen is the same so they weren't affected by the patch.
