Ah :) I implemented it here, it would have been great to have picked your brain on it back when implementing MV! c++filt seems hit or miss as to whether it would demangle it. i think ones with dots in it (sse4.2) doesn't work. I also implemented CPU-Dispatch/CPU-Specific from ICC at one point which doesn't demangle at all. It DOES remind me, I had target-clones implemented at one point and under review, but never got back around to it...
