Provides an API to run clang tools (FrontendActions) as standalone tools,
or repeatedly in-memory in a process. This is useful for unit-testing,
map-reduce style applications, source transformation daemons or command line
tools.

The ability to run over multiple translation units with different command
line arguments enables building up refactoring tools that need to apply
transformations across translation unit boundaries.

See tools/clang-check/ClangCheck.cpp for an example.

argument to driver and frontend, to control the maximum number of notes so
produced (default 10). Fix APValue printing to be able to pretty-print all
APValue types, and move the testing for this functionality from a unittest to
a -verify test now that it's visible in clang's output.

tools that match on the C++ ASTs. The main interface is in ASTMatchers.h,
an example implementation of a tool that removes redundant .c_str() calls
is in the example RemoveCStrCalls.cpp.

Fixes PR9886.

This patch simplifies writing of standalone Clang tools. As an
example, we add clang-check, a tool that runs a syntax only frontend
action over a .cc file. When you integrate this into your favorite
editor, you get much faster feedback on your compilation errors, thus
reducing your feedback cycle especially when writing new code.

The tool depends on integration of an outstanding patch to CMake to
work which allows you to always have a current compile command
database in your cmake output directory when you set
CMAKE_EXPORT_COMPILE_COMMANDS.

the first step towards a standalone Clang tool infrastructure.
The plan is to make it easy to build command line tools that run over
the AST of source files in a project outside of the build system.

It would be nice to propagate this into the other functions to replace
LLVM_LINK_COMPONENTS and friends, but I don't plan to do that.

The next step is to import http://www.itk.org/Wiki/CMakeMacroParseArguments to
make the empty string parameter unnecessary.

This removes the final dependency edge from any lib outside of CodeGen
to core.  As a result we can, and do, trim the dependency on core
from libclang, PrintFunctionNames, the unit tests and c-index-test.
While at it, review and trim other unneeded dependencies.
