* string.c (rb_str_hash): avoid calling rb_enc_str_asciionly_p().
* string.c (rb_str_replace): avoid redundant calling rb_str_new4(). * string.c (str_replace): factor out replacement from rb_str_replace() without type check nor discarding the destination contents. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@23565 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
