Previously the code that parsed debug info to create lldb's Symbol objects such as Variable, Type, Function, etc was tightly coupled to the AST reconstruction code. This made it difficult / impossible to implement functions such as ParseDeclsForContext() that were only supposed to be operating on clang AST's. By splitting these apart, the logic becomes much cleaner and we have a clear separation of responsibilities. llvm-svn: 349383
