introduce new YARV insn newhashfromarray.
* insns.def (newhashfromarray): added to replace `core_hash_from_ary` method to eliminate method call overhead. On my environment, I got the following benchmark results: x = {x: 1} modified: 7864988.6 i/s trunk: 6004098.1 i/s - 1.31x slower x = {x: 1, y: 2} trunk: 6127338.4 i/s modified: 5232380.0 i/s - 1.17x slower x = {x: 1, y: 2, z: 3} modified: 6089553.1 i/s trunk: 5249333.5 i/s - 1.16x slower This trivial improvement should be reconsider because of usage of this instruction. * compile.c: ditto. * defs/id.def, vm.c: remove unused functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65343 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
