a command line argument adjuster, which is responsible for command line
arguments modification before the arguments are used to run a frontend action.
Define class ClangSyntaxOnlyAdjuster implements ArgumentsAdjuster interface.
This class converts input command line arguments to the "syntax check only"
variant.

The chdir is not the perfect fix, as it is thread hostile. The
real fix will be to make -working-dir work correctly, which will
take time to implement. Before that, the tooling library cannot
be used concurrently.

We currently want to look whether PWD is available - if PWD is available it will
get us the non-resolved current path, while fs::current_path will resolve
symlinks. The long term fix is to not rely on that behavior any more.

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.

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.

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.
