When comparing the source range of a declaration against the region of
interest (e.g., as used by clang_getCursor()), count the decl-specifier-seq as part of the source range, as we do for clang_annotateTokens(). Makes clang_getCursor() work properly for the result types of functions, for example. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119514 91177308-0d34-0410-b5e6-96231b3b80d8
