* See comment at head of compilerplugins/clang/unusedmember.cxx for description. * Moved isAllRelevantCodeDefined from loplugin:fakebool to PluginHandler for reuse. (Made it a member function so that it can reuse its two RecordCompleteMap instances across different loplugins. Probably safer lifecycle-wise to have them as PluginHandler members than to have them as static local variables in function isAllRelevantCodeDefined.) * Need Plugin::ignoreLocation overload for TypeLoc now, thanks to UnusedMember::VisitElaboratedTypeLoc. * UETT_PreferredAlignOf was split off UETT_AlignOf with <https://github.com/ llvm/llvm-project/commit/6822bd79ac43f267613f1615bf60407103e24dba> "PR26547: alignof should return ABI alignment, not preferred alignment". * RecursiveASTVisitor::TraverseAlignedAttr traverses into the attribute's argument only since <https://github.com/llvm/llvm-project/commit/ f26d551387f032e05e5e6551605b150f38c3f5b2> "Do not look through pack expansions when looking for unexpanded parameter packs".
