Summary: The existing CTU mechanism imports `FunctionDecl`s where the definition is available in another TU. This patch extends that to VarDecls, to bind more constants. - Add VarDecl importing functionality to CrossTranslationUnitContext - Import Decls while traversing them in AnalysisConsumer - Add VarDecls to CTU external mappings generator - Name changes from "external function map" to "external definition map" Reviewers: NoQ, dcoughlin, xazax.hun, george.karpenkov, martong Reviewed By: xazax.hun Subscribers: Charusso, baloghadamsoftware, mikhail.ramalho, Szelethus, donat.nagy, dkrupp, george.karpenkov, mgorny, whisperity, szepet, rnkovacs, a.sidorin, cfe-commits Tags: #clang Differential Revision: https://reviews.llvm.org/D46421 llvm-svn: 358968
