clang-p2996/llvm/test/CodeGen/ARM/popcnt.ll
Sergei Barannikov 411d31ad69 Partially revert 92e18ffd80 (#101673) 
It is likely to cause stage2 build failures:

https://lab.llvm.org/buildbot/#/builders/122/builds/389
https://lab.llvm.org/buildbot/#/builders/79/builds/552

I don't have an ARM machine to investigate, so I'm just reverting ARM
changes to see if it helps make the bots green again.
