* gc.c (rgengc_check_shady): add new WB miss checking
on RGENGC_CHECK_MODE >= 2. (1) Save bitmaps before marking (2) Run full marking (3) On each traceable object, (a) object was not oldgen (== newly or shady object) && (b) parent object was oldgen && (c) parent object was not remembered && (d) object was not rememberd then, it should be WB miss. This idea of this checker is by Masaya Tarui <tarui@ruby-lang.org>. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@41564 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
