Edwin Vane a98217a2b6 Avoid parallelism problems generating lit.site.cfgs
extra/test/cpp11-migrate/Makefile was using the same tmp file for generating
lit.site.cfg for two different directories. Parallelism caused conflicts so now
using differently named temp files.

Edwin Vane b1bb4c2dbb Fix recursive make in clang-tools-extra
Autoconf make (all) now properly recurses from tools/extra/Makefile into
tools/extra/test/Makefile and tools/extra/test/cpp11-migrate/Makefile. The
'all' target is responsible for creating lit config files and autogenerating
tests. Subsequent 'check-all' targets will properly work.

Re-enabling UseAuto/iterator.cpp test.

General clean-up of clang-tools-extra makefiles; removing dead targets and
removing duplicated pieces of llvm/Makefile.rules.

Edwin Vane 4b80752550 Don't use 'exit' in lit script
Some buildbots use a shell that doesn't know 'exit'. So instead of using XFAIL
for UseAuto/iterator.cpp (since this problem doesn't exist for cmake) leave the
'grep' command and turn off the others.

Edwin Vane ca5a85fad4 Turning off UseAuto/iterator.cpp test until recursive make issue fixed
The way 'make check-all' causes configuration files to be generated results in
the cpp11-migrate/Makefile not being triggered to generated any files. These
files are necessary for UseAuto/iterator.cpp to run. Turning off this test
until the problem is fixed properly.

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).

Edwin Vane 24b4bb06ed Custom lit.site.cfg configuration for cpp11-migrate
To afford hand-written tests access to any auto-generated headers, a
lit.site.cfg is now created for cpp11-migrate's test directory providing a new
config.substition. Tests can refer to %gen_root in the LIT script.

Removed use of --param clang_site_config. Not necessary when running
tests using the build system.

Edwin Vane 12db04f820 Fixing a "multiple rules generate X" warning from ninja
CMake's Ninja generator was not detecting that test/lit.site.cfg.in and
test/subdir/../lit.site.cfg.in were really the same file. Ninja noticed this
and complained as both appeared as targets (for the missing file rule). Now
canonicalizing the path to ensure the paths presented to CMake are identical
and the duplication is now fixed.

Edwin Vane 8b526f22c6 Add support for auto-generating LIT tests by the build
autoconf and CMake flavours both updated to auto-generate files for use
in cpp11-migrate's LIT tests.

Auto-generated files are placed in the build directory under
test/cpp11-migrate/autogen. The directory structure past this point
mirrors the structure in the source directory under test/cpp11-migrate.
A lit.site.cfg is generated in test/cpp11-migrate/autogen to describe
the new test suite. When LIT runs, it runs the standard testsuite and
now also the auto-generated testsuite.

Edwin Vane 4ad00b46fb Fix -use-nullptr problems with assert()
If a cast expression (NullToPointer) is detected in a function-like macro
parameter, we should use the spelling location instead of the expansion
location. Using SourceManager::getFileLoc() fixes this problem.

Also added testcases for this bug.

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.

Manuel Klimek 8c651f0974 Implements support for specifying multiple ranges.
This is backwards compatible with earlier integrations.
Also adds a basic test and a test for the ranges integration.

You can now run:
clang-format -offset=42 -length=15 -offset=150 -length=22
To re-format the ranges (42, +15) and (150, +22).

Edwin Vane 44c3145938 Add use-nullptr transform to cpp11-migrate
This transform converts the usage of null pointer constants (e.g. NULL, 0,
etc.) in legacy C++ code and converts them to use the new C++11 nullptr
keyword.
- Added use-nullptr transform.
- Added C++11 support to the final syntax check. Used ArgumentAdjuster class to
  add -std=c++11 option to the command line options.
- Added tests for use-nullptr transform.
- Added tests that exercises both loop-convert and use-nullptr in the source
  file.

TODO: There's a known bug when using both -loop-convert and -use-nullptr at the
      same time.

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.

David Blaikie efae14e96c Fix tests to be more robust (to older versions of grep, lesser lit-like test runners, etc)
Seems I had a problem with my version of grep, when run by lit, not supporting
the \s escape. This seems to fix it for me & I'll be getting the buildbots to
run these tests too to keep an eye on them (actually loop-convert tests still
fail when run via a make build, so that'll be addressed in a future commit). I
could use [[:space:]] to generalize over other whitespace but that seemed
unnecessarily verbose when the flexibility wasn't actually required by the
current text of the tests.

Also I just simplified a lot of the loop-convert tests (removing the
unecessary temp file deletion at the start, removing the unnecessary && for
FileCheck, etc).

The remove-cstr-calls/basic.cpp changes were necessitated by an out of tree
lit-like test runner that's a bit less fantastic about escaping. They were
modeled on existing tooling test cases in Clang, with thanks to Manuel Klimek
for the pointers.

Sam Panzer 4cf99cfdc7 loop-convert, a C++11 for loop modernizer
A new Clang-based tool which converts for loops to use the range-based
syntax new to C++11. Three kinds of loops can be converted:
 - Loops over statically allocated arrays
 - Loops over containers, using iterators
 - Loops over array-like containers, using operator[] and at()

Each transformation is assigned a confidence level by the tool. The
minimum require confidence level to actually apply the transformation
can be specified on the command line, but the default level should be
fine for most code.

Like other tools based on RefactoringTool, it is easiest to use this
tool with a compilation database.
