Raphael Isemann e9bc35fe06 [ASTImporter] Add an ImportImpl method to allow customizing Import behavior.
Summary:
We are currently implementing support in LLDB that reconstructs the STL templates from
the target program in the expression evaluator. This reconstruction happens during the
import process from our debug info AST into the expression evaluation AST, which means
we need a way to intercept the ASTImporter import process.

This patch adds an protected ImportImpl method that we can overwrite in LLDB to implement
our special importing logic (which is essentially just looking into a C++ module that is attached to
the target context). Because ImportImpl has to call MapImported/AddToLookup for the decls it
creates, this patch also exposes those via a new unified method and checks that we call it when
importing decls.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
