clang-p2996/llvm/test/Transforms/LoopIdiom/RISCV/popcnt.ll
Alex Bradbury 33d008b169 [RISCV] Update recently ratified Zb{a,b,c,s} extensions to no longer be experimental 
Agreed policy is that RISC-V extensions that have not yet been ratified
should be marked as experimental, and enabling them requires the use of
the -menable-experimental-extensions flag when using clang alongside the
version number. These extensions have now been ratified, so this is no
longer necessary, and the target feature names can be renamed to no
longer be prefixed with "experimental-".
