The command-line for clang-apply-replacements was being mangled due to an
uninitialized variable. gasp! Now fixed.

llvm-svn: 192033

Summary:
The clang-apply-replacements process is now invoked to apply
replacements between applying transforms. This resulted in a massive
simplification of the tool:
- FileOverrides class no longer needed.
- Change tracking and code formatting no longer needed.
- No more dependency on libclangApplyReplacements.
- Final syntax check is easier to do directly now than with a separate
  header/source pair.

Replacement handling stuff abstracted into a new header/source pair to
de-clutter ClangModernize.cpp somewhat.

Tests updated.

clang-apply-replacements unittest Makefile wasn't linking in TransformUtils.

The tool now supports a collection of arguments to turn on and provide settings
for the formatting of code affected by applying replacements:
* --format turns on formatting (default style is LLVM)
* --style controls code style settings
* --style-config allows one to explicitly indicate where a style config file
  lives.

The libclangApplyReplacements interface has a new function to turn Replacements
into Ranges to be used with tooling::reformat().

The LoopConvert transform makes use of data structures it builds up over
the course of transforming a TU. Until now, these data structures
weren't being cleared out before the next TU was being processed.

Fixes PR17253.

Options that leak from other parts of LLVM are now pruned out of -help.

-version output is specific to clang-apply-replacements now.

This patch also fixes the case where a compilation database is autodetected from
source but the file itself cannot be found in the compilation database, it then
ignores the compilation database and transforms the file with c++11 support.

- Limit the transform to const-ref and non-const value parameters only.
- Do not generate a replacement when the type is already a value.

-include/-exclude and friends have been marked as hidden options until this
point. This is no longer necessary. Update the docs to describe their effect.

clang-modernize can now transform headers properly and the experimental
-headers option is no longer necessary.

Remember, at least -include is necessary for indicating which headers
are allowed to be changed.

If transformations lead to changes that do not need reformatting, the
current strategy will not write those files. With this patch, we just
update the overall state with the changes due to reformatting, and then
write out everything.

There is no reason to expect this tool to be limited to C++11, it seems
very likely to be of on-going interest. It seems likely to be useful for
modernizing even as new libraries come out in TSes and other formats
than a complete standard. Fundamentally, we need something a bit more
general. After some discussion on the list, going with
'clang-modernize'.

I've tried to do a reasonably comprehensive job of fixing up the names,
but I may still have missed some. Feel free to poke me if you spot any
fallout here. Things I've tried reasonably hard to find and fix:

- cpp11-migrate -> clang-modernize
- Migrator -> Modernizer
- Clean up the introductory documentation that was C++11 specific.

I'll also point out that this tool continues to delight me. =] Also,
a huge thanks to those who have so carefully, thoroughly documented the
tool. The docs here are simply phenomenal. Every tool should be this
well documented. I hope I have updated the documentation reasonably
well, but I'm not very good at documentation, so review much
appreciated.

The NoProblemsDependencies.modularize test is failing on many buildbots.
I have also reverted the change in 189904 to disable that test for MSVC.
