https://bugs.webkit.org/show_bug.cgi?id=118486 Reviewed by Geoffrey Garen. I borked dominators in: http://trac.webkit.org/changeset/152431/branches/dfgFourthTier/Source/JavaScriptCore/dfg/DFGDominators.h This patch also adds some debug support, and fixes the loop that adds a block to an already-existing natural loop. Note that we currently don't take that path in most programs, but it will arise, for example if you use 'continue' - though you'd have to use it rather cleverly since the bytecode will not jump to the loop header in most uses of 'continue'. * dfg/DFGDominators.cpp: (JSC::DFG::Dominators::dump): (DFG): * dfg/DFGDominators.h: (JSC::DFG::Dominators::dominates): (Dominators): * dfg/DFGNaturalLoops.cpp: (JSC::DFG::NaturalLoops::compute): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@153272 268f45cc-cd09-0410-ab3c-d52691b4dbfc
