[Modules] Cope better with top-level declarations loaded after being declared in the current translation unit <rdar://problem/13189985>. These two related tweaks to keep the information associated with a given identifier correct when the identifier has been given some top-level information (say, a top-level declaration) and more information is then loaded from a module. The first ensures that an identifier that was "interesting" before being loaded from an AST is considered to be different from its on-disk counterpart. Otherwise, we lose such changes when writing the current translation unit as a module. Second, teach the code that injects AST-loaded names into the identifier chain for name lookup to keep the most recent declaration, so that we don't end up confusing our declaration chains by having a different declaration in there. llvm-svn: 174895 2013-02-12 02:16:18 +08:00			`// RUN: rm -rf %t`
[modules] Simplify -cc1 interface for enabling implicit module maps. We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789 2015-06-16 08:08:24 +08:00			`// RUN: %clang_cc1 -fmodules -fimplicit-module-maps -fmodules-cache-path=%t -I %S/Inputs %s -verify -Wno-objc-root-class`
