first writing the changed files to a temporary location and then overwriting
the original files atomically.
Also adds a RewriterTestContext to aid unit testing rewrting logic in general.

We don't create any declaration to mark the explicit instantiation of function
templates other than the instantiation itself, so visit that when traversing
the function template decl.
This is a temporary fix, pending the creation of a Decl node to represent the
explicit instantiation.

* Work around build failures due to gcc 4.2 bugs.
* Remove BodyIndexer::TraverseCXXOperatorCallExpr, which was not being called
prior to this change, and whose presence disables a RecursiveASTVisitor
stack space optimization after this change.

all instantiations of a template when we visit the canonical declaration of the
primary template, rather than trying to match them up to the partial
specialization from which they are instantiated. This fixes a bug where we
failed to visit instantiations of partial specializations of member templates of
class templates, and naturally extends to allow us to visit instantiations where
we have instantiated only a declaration.

templates. In an implicit instantiation of a member class, any member
templates don't get instantiated, so the existing check which only visited
the instantiations of a defined template skipped these templates'
instantiations.
Since there is only a single declaration of a member template of a class
template specialization, just use that to determine whether to visit the
instantiations. This introduces a slight inconsistency in that we will
visit the instantiations of such templates whether or not they are
defined, but we never visit a declared-but-not-defined instantiation, so
this turns out to not matter.

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.
