Guillaume Papin ebde78c4c6 cpp11-migrate: Register the transforms automatically using llvm::Registry
With this change each transform now register a factory. The factories are
registered using an llvm::Registry which makes them available globally.

Edwin Vane aae33677f5 cpp11-migrate: Tidying up
* 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

Edwin Vane ba6b32d1ce cpp11-migrate: Transforms honour header modification flag
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.

Edwin Vane 62c013db6c cpp11-migrate: Transform now responsible for applying replacements
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.

Edwin Vane 4e11abb59b cpp11-migrate: Transform now responsible for file content overriding
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.

Edwin Vane e0a7d9ceff cpp11-migrate: Replace file override container
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.

Edwin Vane a6bbcdd707 cpp11-migrate: New mechanism for overriding file contents
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.

Edwin Vane b76a13eb4e cpp11-migrate: Transforms collect timing data.
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.

Edwin Vane b40bf83eab Transform for loops over pseudo-arrays only if begin/end members exist
For loops using pseudo-arrays, classes that can be used like arrays from
the Loop Convert Transform's point of view, should only get transformed
if the pseudo-array class has begin()/end() members for the
range-based for-loop to call.

Free versions of begin()/end() should also be allowed but this is an
enhancement for another revision.

Edwin Vane fa58b26a50 Stop LoopConvert removing DeclStmts from selection/iteration condition clauses
If the LoopConvert Transform detects an alias for the loop variable, it
attempts to use that name in the resulting range-based for loop while removing
the original DeclStmt for the variable. That removal produced bad code when the
declaration was in the condition of an if, switch, while, or for stmt. This
revision fixes the problem by simply replacing the declaration with a use of
the alias variable.

Edwin Vane 8581648838 lib-ified core cpp11-migrate functionality to support unit tests
Summary:
Transform.* and Transforms.* moved to form a new library: libmigrateCore.
#includes updated to point to new header locations.

To support autoconf build, Cpp11Migrate.cpp moved to new subdirectory 'tool'
which also contains build files for creating final binary.

CMake and autoconf updated to build the new library and link it with
cpp11-migrate and with cpp11-migrate unit tests.

Dummy unit tests replaced with simple, but real, tests for Transform's public
interface.

TODO: Lib-ifying the transforms to further simplify build of cpp11-migrate.

Edwin Vane 61af48ce4e Improve loop convert's variable aliasing
Loop convert's variable name aliasing may cause issues if the variable is
declared as a value (copy). The converted loop will declare the variable as a
reference which may inadvertently cause modifications to the container if it
were used and modified as a temporary copy.

This is fixed by preserving the reference or value qualifiers of the aliased
variable. That is, if the variable was declared as a value the loop variable
will also be declared as a value and similarly for references.

Edwin Vane 4f05d7143f Have LoopConvert use 'auto &&' where necessary
For iterators where the dereference operator returns by value, LoopConvert
should use 'auto &&' in the range-based for loop expression.

If the dereference operator returns an rvalue reference, this is deemed too
strange and the for loop is not converted.

Moved test case from iterator_failing.cpp to iterator.cpp and added extra
tests.

Fixes PR15437.

Edwin Vane 37fea69391 Fix for combined loop and nullptr convert tests
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.
