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.

"#include MACRO(STUFF)".
-As an inclusion position for the included file, use the file location of the file where it
was included but *after* the macro expansions. We want the macro expansions to be considered
as before-in-translation-unit for everything in the included file.
-In the preprocessing record take into account that only inclusion directives can be encountered
as "out-of-order" (by comparing the start of the range which for inclusions is the hash location)
and use binary search if there is an extreme number of macro expansions in the include directive.

the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.
This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator. We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

Introduce PreprocessingRecord::rangeIntersectsConditionalDirective() which returns
true if a given range intersects with a conditional directive block.

fails within a call to a constexpr function. Add -fconstexpr-backtrace-limit
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.

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.
