[Modules] Emit the module file paths as dependencies of the PCH when we are building one. This is because the PCH is tied to the module files, if one of the module files changes or gets removed the build system should re-build the PCH file. rdar://16321245 llvm-svn: 203885

Allow multiple modules with the same name to coexist in the module cache To differentiate between two modules with the same name, we will consider the path the module map file that they are defined by* part of the ‘key’ for looking up the precompiled module (pcm file). Specifically, this patch renames the precompiled module (pcm) files from cache-path/<module hash>/Foo.pcm to cache-path/<module hash>/Foo-<hash of module map path>.pcm In addition, I’ve taught the ASTReader to re-resolve the names of imported modules during module loading so that if the header search context changes between when a module was originally built and when it is loaded we can rebuild it if necessary. For example, if module A imports module B first time: clang -I /path/to/A -I /path/to/B ... second time: clang -I /path/to/A -I /different/path/to/B ... will now rebuild A as expected. * in the case of inferred modules, we use the module map file that allowed the inference, not the __inferred_module.map file, since the inferred file path is the same for every inferred module. llvm-svn: 206201
