Summary:
An AtomicChange is used to create and group a set of source edits, e.g.
replacements or header insertions. Edits in an AtomicChange should be related,
e.g. replacements for the same type reference and the corresponding header
insertion/deletion.
An AtomicChange is uniquely identified by a key position and will either be
fully applied or not applied at all. The key position should be the location
of the key syntactical element that is being changed, e.g. the call to a
refactored method.
Next step: add a tool that applies AtomicChange.

In bigger projects like an Operating System, the same source code is
often compiled in slightly different ways. This could be the difference
between PIC and non-PIC code for static vs dynamic libraries, it could
also be the difference between size optimised versions of tools for
ramdisk images. At the moment, the compilation database has no way to
distinguish such cases. As first step, add a field in the JSON format

The new error information contains the type of error (e.g. overlap or bad file path)
and the replacement(s) that is causing the error. This enables us to resolve some errors.
For example, for insertion at the same location conflict, we need to know the
existing replacement which conflicts with the new replacement in order to calculate
the new position to be insert before/after the existing replacement (for merging).

Now two replacements are considered order-independent if applying them in
either order produces the same result. These include (but not restricted
to) replacements that:
- don't overlap (being directly adjacent is fine) and
- are overlapping deletions.
- are insertions at the same offset and applying them in either order
has the same effect, i.e. X + Y = Y + X if one inserts text X and the
other inserts text Y.

No behavioral change intended. The change makes iterating the replacements set more intuitive in Replacements class implementation. Previously, insertion is ordered before an deletion/replacement with the same offset, which is counter-intuitive for implementation, especially for a followup patch to support adding insertions around replacements.
With the current ordering, we only need to make `applyAllReplacements` iterate the replacements set reversely when applying them so that deletion/replacement is still applied before insertion with the same offset.

Two replacements are considered order-independent if one of the following conditions is true:
- They do not overlap. (This is already supported.)
- One replacement is insertion, and the other is a replacement with
length > 0, and the insertion is adjecent to but not contained in the
other replacement. In this case, the replacement should always change
the original code instead of the inserted text.

This patch introduced the ability to decide at runtime whether to parse
JSON compilation database command lines using Gnu syntax or Windows
syntax. However, there were many existing unit tests written that
hardcoded Gnu-specific paths. These tests were now failing because
the auto-detection logic was choosing to parse them using Windows
rules.
This resubmission of the patch fixes this by introducing an enum
which defines the syntax mode, which defaults to auto-detect, but
for which the unit tests force Gnu style parsing.

This differs from the previous version by being more careful about template
instantiation/specialization in order to prevent errors when building with
clang -Werror. Specifically:
* begin is not defined in the template and is instead instantiated when Head
is. I think the warning when we don't do that is wrong (PR28815) but for now
at least do it this way to avoid the warning.
* Instead of performing template specializations in LLVM_INSTANTIATE_REGISTRY
instead provide a template definition then do explicit instantiation. No
compiler I've tried has problems with doing it the other way, but strictly
speaking it's not permitted by the C++ standard so better safe than sorry.
Original commit message:
Currently the Registry class contains the vestiges of a previous attempt to
allow plugins to be used on Windows without using BUILD_SHARED_LIBS, where a
plugin would have its own copy of a registry and export it to be imported by
the tool that's loading the plugin. This only works if the plugin is entirely
self-contained with the only interface between the plugin and tool being the
registry, and in particular this conflicts with how IR pass plugins work.
This patch changes things so that instead the add_node function of the registry
is exported by the tool and then imported by the plugin, which solves this
problem and also means that instead of every plugin having to export every
registry they use instead LLVM only has to export the add_node functions. This
allows plugins that use a registry to work on Windows if

One problem in clang-tidy and other clang tools face is that there is no
way to lookup an arbitrary name in the AST, that's buried deep inside Sema
and might not even be what the user wants as the new name may be freshly
inserted and not available in the AST.
A common use case for lookups is replacing one nested name with another
while minimizing namespace qualifications, so replacing 'ns::foo' with
'ns::bar' will use just 'bar' if we happen to be inside the namespace 'ns'.
This adds a little helper utility for exactly that use case.

This CL adds a new attribute 'arguments', an array of strings, which
specifies the exact command line arguments. If 'arguments' is available
in the compilation database, it is preferred to 'commands'.
Currently there is no plan to retire 'commands': there are enough

FixedCompilationDatabase (FCD) requires that the arguments it consumes after
'--' must not include positional parameters or the argv[0] of the tool. This
patch relaxes those restrictions.

These allow clients to retrieve persistent AST objects (ASTUnits) which
can be used in an ad-hoc manner after parsing.
To accommodate this change, the code for processing a CompilerInvocation
using a FrontendAction has been factored out to FrontendActionFactory, and
a new base class, ToolAction, has been introduced, allowing the tool to do
arbitrary things with each CompilerInvocation. This change was necessary
because ASTUnit does not use the FrontendAction interface directly.
This change also causes the FileManager in ClangTool to use shared ownership.
This will become necessary because ASTUnit takes shared ownership of
FileManager (ClangTool's FileManager is currently unused by ASTUnit; this
is a FIXME). As shown in the tests, any client of ToolInvocation will
need to be modified to use shared ownership for FileManager.

This replaces the custom code in RefactoringTool::saveRewrittenFiles() which

This moves the code to Job.cpp, which seems like a more natural fit,
and replaces the "is this a JobList? is this a Command?" logic with
a virtual function call.
It also removes the code duplication between PrintJob and
PrintDiagnosticJob and simplifies the code a little.
There's no functionality change here, except that the Executable is
now always printed within quotes, whereas it would previously not be
quoted in crash reports, which I think was a bug.

During the transition of clang::tooling::Replacements from std::set to

One day soon, tooling::Replacements will be changed from being implemented as
an std::set to being implemented as an std::vector. Until then, some new code
using vectors of Replacements would enjoy having a version of
applyAllReplacements that takes a vector.

The big changes are:
- Deleting Driver/(Arg|Opt)*
- Rewriting includes to llvm/Option/ and re-sorting
- 'using namespace llvm::opt' in clang::driver
- Fixing the autoconf build by adding option everywhere
As discussed in the review, this change includes using directives in
header files. I'll make follow up changes to remove those in favor of

It turns out that several implementations go through the trouble of
setting up a SourceManager and Lexer and abstracting this into a
function makes usage easier.
Also abstracts SourceManager-independent ranges out of
tooling::Refactoring and provides a convenience function to create them
from line ranges.

RefactoringTool::run() always writes the result of rewrites to disk.
Instead, make this optional and provide a method for getting the
refactoring results in a memory buffer instead.
Also made ClangTool polymorphic so RefactoringTool could inherit from it
to properly express the IS-A relationship. This change also provides
access to ClangTool's public interface, e.g. mapVirtualFile() which is
important once refactored buffers start living in memory instead of on
disk.
