_mjit_compile_getivar.erb: optimize IC-hit getivar
by inlining index (and serial to invalidate that) and simplifying the branch by using JIT cancellation. mjit_compile.inc.erb: use the above file mjit_compile.c: copy USE_IC_FOR_IVAR definition. will move this to another shared file later. common.mk: add new dependency test/ruby/test_jit.rb: cover this case === Optcarrot benchmark === ``` $ benchmark-driver benchmark.yml --rbenv '2.0.0::2.0.0-p648;before::before --disable-gems;before+JIT::before --disable-gems --jit;after::after --disable-gems;after+JIT::after --disable-gems --jit' -v --repeat-count 24 2.0.0: ruby 2.0.0p648 (2015-12-16 revision 53162) [x86_64-linux] before: ruby 2.6.0dev (2018-10-14 trunk 65072) [x86_64-linux] before+JIT: ruby 2.6.0dev (2018-10-14 trunk 65072) +JIT [x86_64-linux] after: ruby 2.6.0dev (2018-10-14 trunk 65072) [x86_64-linux] last_commit=_mjit_compile_getivar.erb: optimize IC-hit getivar after+JIT: ruby 2.6.0dev (2018-10-14 trunk 65072) +JIT [x86_64-linux] last_commit=_mjit_compile_getivar.erb: optimize IC-hit getivar Calculating ------------------------------------- 2.0.0 before before+JIT after after+JIT Optcarrot Lan_Master.nes 36.065 53.896 71.565 53.856 84.747 fps Comparison: Optcarrot Lan_Master.nes after+JIT: 84.7 fps before+JIT: 71.6 fps - 1.18x slower before: 53.9 fps - 1.57x slower after: 53.9 fps - 1.57x slower 2.0.0: 36.1 fps - 2.35x slower ``` git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65073 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
