* compile.c (iseq_compile_each): share InlineCache during same
instance variable accesses. Reducing memory consumption, rasing cache hit rate and rasing branch prediction hit rate are expected. A part of [Bug #12274]. * iseq.h (struct iseq_compile_data): introduce instance variable IC table for sharing. * iseq.c (prepare_iseq_build, compile_data_free): construct/destruct above table. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54976 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
