[ruby-core:59606] [ruby-trunk - misc #9188] r43870 make benchmark/bm_so_k_nucleotide.rb slow

Issue #9188 has been updated by tmm1 (Aman Gupta).

The new opt_aset_str and opt_aref_str instructions only affect string literals, and all strings literals are already in the fstring table in 2.1.
I don't think there is any possible performance regression with this technique.
