[lanai] Simplify small section check in LowerGlobalAddress and treat ldata sections specially. Move the check for the code model into isGlobalInSmallSectionImpl and return false (not in small section) for variables placed in sections prefixed with .ldata (workaround for a tool limitation). llvm-svn: 289832
