[Luís Marques via Phabricator via llvm-commits]

In CoreMark-Pro, when the execution model is 1 instr == 1 cycle, with this patch the results I get is that sha-test improves by +1.43% in RV64 (GC, LP64D). For all other sub-benchmarks the performance differences round to 0.00%. There's no change to sha-test in RV32 before and after the patch.
