This is a necessary prerequisite for debugging with modules. The .pcm files become containers that hold the serialized AST which allows us to store debug information in the module file that can be shared by all object files that were built importing the module. rdar://problem/19104245 This reapplies r230044 with a fixed configure+make build and updated dependencies. Take 3. llvm-svn: 230305
