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
