This moves classes for storing and applying replacements to separate
files. These classes specifically are used by clang-format which doesn't
have any other dependencies on clangAST. Thereby, the size of
clang-format's binary can be cut roughly in half and its build time sped
up.

There's probably never a good reason to iterate over unique_ptrs. This
lets us use range-for and say Job.foo instead of (*it)->foo in a few
places.
llvm-svn: 218938
This was horribly broken due to how the sort predicate works. We would
report a conflict for files with a replacement in the same position but
different names if the length differed. Just ignore paths as this is often
what the user wants. Files can occur with different names (due to symlinks
or relative paths) and we don't ever want to do the same edit in one file
twice.

Only those callers who are dynamically passing ownership should need the
3 argument form. Those accepting the default ("do pass ownership")
should do so explicitly with a unique_ptr now.

Diving into the memory leaks fixed by r213851 there was one case of a
memory leak of a CompilationDatabase due to not properly taking
ownership of the result of "CompilationDatabase::autoDetectFromSource".
Given that both implementations and callers have been using unique_ptr
to own CompilationDatabase objects - make this explicit in the API to
reduce the risk of further leaks.

The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.
Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.
Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.

This corrects long-standing misuses of LLVM's internal config.h.
In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.
The config.h header is private, won't be installed and should no longer be
included by clang or other modules.

All callers were passing in "a.out" or garbage so a sensible default works fine
here as a cleanup.
This also brings about the possibility of adapting the value based on the

The setting can still be changed via Driver::DefaultImageName as needed.

It moves them at the end of the range instead, so an extra erase is needed.
It is strange that this code works without the erase. On the other hand, removing the remove_if will make fail some tests.

It isn't appropriate for a tool to be stomping over the dependency files,
especially if the actual build uses a compiler other than Clang or the tool
cannot find all the headers for some reason (which would cause the existing
dependency file to be deleted).
If a tool actually needs to care about dependency files we can think about
adding a mechanism for getting to this information.

This does;
- clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
- List of targets is added to LLVM_COMMON_DEPENDS.
- all clang libraries and targets depend on generated headers.
You might wonder this would be regression, but in fact, this is little loss.
- Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
- clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
- Each library's dependencies to tblgen'd files might vary along headers' structure.
It made hard to track and update *really optimal* dependencies.
Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

FixedCompilationDatabase (FCD) requires that the arguments it consumes after

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 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.

This will allow us to delete the JSON parser from llvm.
The biggest change is a general change of strategy - instead
of storing StringRef's to the values for the command line and
directory in the input buffer, we store ScalarNode*'s. The
reason is that the YAML parser's getRawValue on ScalarNodes
returns a string that includes the quotes in case of double
quoted strings.
For the same reason we're removing the JSON parsing part of
the command line parsing - this means an extra copy for a
command line when it is requested (and only when it is requested).

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

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.
