insns.def: add opt path for Hash#[] and Hash#[]= used with str literal keys
* insns.def (opt_aref_with): new instruction to optimize Hash#[], removing any allocation overhead when used with a string literal key. Patch by normalperson (Eric Wong). [ruby-core:59640] [Bug #9382] * insns.def (opt_aset_with): new instruction to optimize Hash#[]= * compile.c (iseq_compile_each): compiler shortcuts for new instructions * hash.c (static VALUE rb_hash_compare_by_id_p): fix documentation for Hash#compare_by_identity to reflect frozen string sharing * test/ruby/test_hash.rb (class TestHash): test for new behavior git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44551 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
