introduced by using decls are hidden even if their template parameter lists
or return types differ from the "overriding" declaration.

Propagate using shadow declarations around more effectively when looking up
template-ids.  Reperform lookup for template-ids in member expressions so that
access control is properly set up.

Fix some number of latent bugs involving template-ids with totally invalid
base types.  You can only actually get these with a scope specifier, since
otherwise the template-id won't parse as a template-id.

isIntegralType(). The two should have the same meaning, but currently
don't (!).

Currently, all AST consumers are located in the Frontend library,
meaning that in a shared library configuration, Frontend has a
dependency on Rewrite, Checker and CodeGen.  This is suboptimal for
clients which only wish to make use of the frontend.  CodeGen in
particular introduces a large number of unwanted dependencies.

This patch breaks the dependency by moving all AST consumers with
dependencies on Rewrite, Checker and/or CodeGen to their respective
libraries.  The patch therefore introduces dependencies in the other
direction (i.e. from Rewrite, Checker and CodeGen to Frontend).

After applying this patch, Clang builds correctly using CMake and
shared libraries ("cmake -DBUILD_SHARED_LIBS=ON").

N.B. This patch includes file renames which are indicated in the
patch body.

Changes in this revision of the patch:
 - Fixed some copy-paste mistakes in the header files
 - Modified certain aspects of the coding to comply with the LLVM
   Coding Standards
