With this change each transform now register a factory. The factories are
registered using an llvm::Registry which makes them available globally.

* Some file headers were missing for files in Core/
* Some headers were included but not necessary
* CMakeLists.txt was linking in LLVMSupport even though CMakeLists in subdirs
were linking it in too.
* StringRefisation of constructors of types in FileOverrides.h
* Other misc cleanups

Transforms will now make changes to headers if header modifications have been
enabled.
FIXME: Only UseNullptr contains a cursory header modification test. Other
transforms should have them too.
llvm-svn: 184197
To make it possible for replacements made to headers as part of transforming
one translation unit to not be visible to the transform of other translation
units, Transform now handles replacement application as part of its
end-of-source handling. Several things were simplified as a result:
- The duplicated code in every transform for applying replacements is now gone
and replaced with one location in Transform.
- RefactoringTool is no longer used since Transform houses the Replacements
structure.
- RewriterContainer is now a private implementation detail of Transform (also
renamed to RewriterManager since its behaviour is slightly different now with
respect to lifetime of objects).
- There's now no distinction between input and output file state.
Misc notes:
- Interface changes reflected in unit tests.
- Replacements for files other than the main file are assumed to be for headers
and stored as such.
llvm-svn: 184194
To better support per-translation unit replacements, any real work is being
moved out of ActionFactory and into Transform. In this revision, that means
file override application.
For simplification, Transform no longer inherits from SourceFileCallbacks.
TransformTest required updating as a result.
llvm-svn: 184098
A more flexible container for storing overrides is required for headers. Before
a source goes through the transform pipeline, any headers it references will be
in their original state and unaffected by transforms applied to other sources.
Therefore overrides for headers need to be kept separate for each source file.
This patch doesn't introduce support for storing header overrides yet. It only
replaces the existing structure and makes any necessary changes to support it.
llvm-svn: 183910
Next step toward supporting migrating headers. Instead of using ClangTool's
ability to override all files at once, use a custom FrontendAction and override
only the source (and eventually headers) the action is about to parse.
Use of newFrontendActionFactory() is replaced with a new factory maker provided
by Transform.
llvm-svn: 183855
Refactored how global options are passed to Transforms to avoid widespread
changes every time a new global option is added.
Tests updated to reflect new interface.
llvm-svn: 183443
Using updated form of newFrontendActionFactory(), Transforms now automatically
measure, if requested, how long it takes to apply a MatchFinder to a source
file. Other per-transform overhead, e.g. applying replacements, is not
currently measured. This behaviour is disabled for now and soon will be
connected to a new command line arg.
llvm-svn: 182942
Added a summary option that enables output to stdout counting the number of
changes each transform has accepted, rejected or deferred.
Patch by Ariel Bernal.
llvm-svn: 176465
Currently, changes made by previous transforms are not kept if a transform
doesn't make any changes itself to a given file. Now file states are propagated
properly through transforms that don't make changes.

The rewriter was previously reading the content buffer from the file itself.
Since we are now keeping the content in memory and writing to the file only
once, the rewriter's buffer (from the file) was not in sync with the
RefactoringTool's buffer. Adding an overrideFileContents call (similar to how
Clang-format handles for this) will resolve this issue.

Instead of writing the result of each transform to disk for every
transform, write the results to buffers in memory and pass those buffers
to the next transform as input. Only write the buffers to disk if the
final syntax check passes.

RefactoringTool::run() no longer writes changes to disk automatically. Updating users of RefactoringTool to explicitly perform the write.

Took existing code from loop-convert tool and made it into a cpp11-migrate
transform. Pattern now set for having transform code in subdirectories. Related
changes:
- Makefile and CMakeLists.txt updated to support source files in
subdirectories.
- At least one transform must be specified. syntax-only tests removed to
reflect this.
- TODO: port over loop-convert tests.
