Lazy Proc allocation for block parameters [Feature #14045] * insns.def (getblockparam, setblockparam): add special access instructions for block parameters. getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and if it is not set this instruction creates a Proc object from a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. setblockparam is similar to setlocal, but set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. * compile.c: use get/setblockparm instead get/setlocal instructions. Note that they are used for method local block parameters (def m(&b)), not for block local method parameters (iter{\|&b\|). * proc.c (get_local_variable_ptr): creates Proc object for Binding#local_variable_get/set. * safe.c (safe_setter): we need to create Proc objects for postponed block parameters when $SAFE is changed. * vm_args.c (args_setup_block_parameter): used only for block local blcok parameters. * vm_args.c (vm_caller_setup_arg_block): if called with VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be a block handler. * test/ruby/test_optimization.rb: add tests. * benchmark/bm_vm1_blockparam*: added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60397 b2dd03c8-39d4-4d8f-98ff-823fe69b080e 2017-10-24 07:13:49 -04:00			`def bp_yield`
