Am I right that this is getInstruction execution time, not llvm-mc execution time? Maybe it makes more sense to measure llvm-mc execution time? I think getInstruction has less than 1% impact on llvm-mc execution time (due to I/O, string formatting, etc.).

I don't see many RISCV tests in the table. What is the avg difference there?

Could the difference be related not to the use of std::bitset, but to the use of lambdas?
