Chandler Carruth 50e3192084 [LCG] Re-implement the basic isParentOf, isAncestorOf, isChildOf, and ... isDescendantOf methods on RefSCCs in terms of the forward edges rather than the parent sets. This is technically slower, but probably not interestingly slower, and all of these routines were already so expensive that they're guarded behind both !NDEBUG and EXPENSIVE_CHECKS. This removes another non-critical usage of parent sets. I've also added some comments to try and help clarify to any potential users the costs of these routines. They're mostly useful for debugging, asserts, or other queries. llvm-svn: 310170		2017-08-05 06:24:09 +00:00
