clang-p2996/llvm/test/Transforms/LoopVectorize/RISCV/interleaved-cost.ll
Luke Lau 366e469db9 [RISCV] Add cost tests for more interleave factors. NFC 
This shows how we're not properly scaling the cost with the number of
factors, i.e. a factor 8 interleave costs the same as a factor 2
interleave at VF=2.
