Edwin Vane 147984a8ad cpp11-migrate: Refactor for driver model of operation
Re-commit of r189691 and r189689 now with a proper autoconf fix.

Massive simplification of how replacements and file overrides are
handled by the migrator:
* Sources and headers are all treated the same.
* All replacements for a given translation unit are stored in the same
  TranslationUnitReplacements structure.
* Change tracking is updated only from main file; no need for
  propagating "is tracking" flag around.
* Transform base class no longer responsible for applying replacements.
  They are simply stored and main() looks after deduplication and
  application.
* Renamed -yaml-only to -serialize-replacements. Same restrictions apply:
  Can only request one transform. New restriction: formatting cannot also
  be turned on since it's basically a transform.
* If -serialize-replacements is requested, changes to files will not be
  applied on disk.
* Changed behaviour of function generating names for serialized
  replacements: Only the main source file goes into the name of the file
  since a file may contain changes for multiple different files.
* Updated HeaderReplacements LIT test for new serialization behaviour.
  * Replaced old test that ensures replacements are not serialized if
    -serialize-replacements is not provided. New version ensures changes
    are made directly to all files in the translation unit.
* Updated unit tests.
  * Due to major simplification of structures in FileOverrides.h, the
    FileOverridesTest is quite a bit simpler now.

Revert "cpp11-migrate: Refactor for driver model of operation"

This reverts commit r189691.
This reverts commit r189689.

This was breaking the phase 1 OS X build for ~2 hours.

https://smooshbase.apple.com/buildbot-internal/builders/phase1%20-%20sanity/builds/9559

I reverted the latter commit since I think the latter depended on the former.

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.

Ariel J. Bernal 1d66e366e9 Fix UseAuto replacing declaration lists with new expressions
UseAuto used to replace declarion lists with new expressons where some
variable were not initialized with new.
This fix checks that every DeclStmt has a VarDecl with an initializer and it
also ensures that all declarations have the same type.

Added tests for multiple declarations and for typedefs.

Ariel J. Bernal eba5189f9a Fix UseAuto replacing variable declaration lists containing non-initialized
variables.

UseAuto used to match initialized variable declarations independently of
whether they were defined in a declaration list or as a single declaration.
Now it matches declaration statements where every variable declaration is
initialized.

Edwin Vane eeed39a583 Use 'auto' with 'new' expressions
For variable declarations initialized with new expressions, use 'auto' for the
type specifier.

The 'auto' replacement happens only when the type of the VarDecl exactly
matches the type of the initializer and the VarDecl is *not* CV-qualified. The
only case that is currently handled is if the pointer type of the VarDecl is
itself CV qualified.

Some improvements need to be made to Clang's TypeLoc information in order for
other CV qualifier cases to be successfully handled. See the new test suite
new_cv_failing.cpp for examples of usages that could be handled with such an
improvement.

Function pointers are, for now, not transformed until the identifier info can
be extracted.

Ariel J. Bernal 3f08aae84f cpp11-migrate segfaults transforming map<string,int>::iterator
cpp11-migrate segfaults when -use-auto tries to resolve initializing 
expression resulting in an expression with cleanups.

- Skip expressions with cleanups from the initializer
- Added test case

Fixes PR15550

Edwin Vane 266b625ca9 Introducing Use-Auto transform for cpp11-migrate
The new Use-Auto transform replaces the type specifier for variable
declarations with the special C++11 'auto' type specifier. For now, the
replacement is done only for variables that are iterators of any of the
std containers and only if the type used is one of those explicitly
allowed by the standard (i.e. not an implementation-specific type).
