Dynamic symbols hash more slowly because they need extra method dispatch in rb_any_hash. I am not sure if dynamic symbols are a realistic use case as hash keys, so this commit only restores performance when comparing against versions of Ruby which lack dsyms. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47854 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
