Aaron Ballman 0f28d62a12 Some of the build bots are unhappy about the overload of the global operator new() because it was accidentally marked noexcept instead of noexcept(false). This should correct those bots.

Angel Garcia Gomez 26fd0e8b62 Create modernize-make-unique check.
Summary: create a check that replaces 'std::unique_ptr<type>(new type(args...))' with 'std::make_unique<type>(args...)'. It was on the list of "Ideas for new Tools". It needs to be tested more carefully, but first I wanted to know if you think it is worth the effort.

Guillaume Papin 68b591079a [clang-tidy] add option to specify build path
Summary:
compile_commands.json is usually generated in the build directory.
Projects like LLVM/Clang enforce out-of-source builds.
This option allow allow such projects to work out of the box, without
moving the compilation database manually.

The naming of the option is similar to the one use by other tools:

    clang-{check,modernize,query,rename,tidy} -p=<build_path> <...>

Alexander Kornienko 3d77768e2a [clang-tidy] Code factorization and cleanup in IdentifierNamingCheck
This is to level the ground a little bit, in preparation for the changes in http://reviews.llvm.org/D13081.

Code factorization replaces all insertions to NamingCheckFailures map with a unique addUsage function that does the job.
There is also no more difference between the declaration and the references to a given identifier, both cases are treated as ranges in the Usage vector. There is also a check to avoid duplicated ranges to be inserted, which sometimes triggered erroneous replacements.

References can now also be added before the declaration of the identifier is actually found; this looks to be the case for example when a templated class uses its parameters to specialize its templated base class.

Patch by Beren Minor!

Manuel Klimek b457b68f8d Fix loop-convert for trivially copyable types.
Previously, we would rewrite:
void f(const vector<int> &v) {
  for (size_t i = 0; i < v.size(); ++i) {
to
  for (const auto &elem : v) {

Now we rewrite it to:
  for (auto elem : v) {
(and similarly for iterator based loops).

Manuel Klimek 143b644238 Fix loop-convert for const references to containers.
Previously we would use a non-const loop variable in the range-based
loop for:
void f(const std::vector<int> &v) {
  for (size_t i = 0; i < v.size(); ++i) {
Now we use const auto&.

Note that we'll also want to use a copy at least for simple types.

Alexander Kornienko 8221ab3499 [clang-tidy] install helper scripts
Scripts are installed in same location as clang-fromat ones, so I think will be good idea to not create dedicated directory.

I checked this patch on my own build on RHEL 6.

Please check it in if it's OK, because I don't have SVN write access.

I think will be good idea to backport this patch to 3.7 release branch.

Probably same should be done for configure build.

Angel Garcia Gomez bb9ca54bbe Another patch for modernize-loop-convert.
Summary:
1. Avoid converting loops that iterate over the size of a container and don't use its elements, as this would result in an unused-result warning.
2. Never capture the elements by value on lambdas, thus avoiding doing unnecessary copies and errors with non-copyable types.
3. The 'const auto &' instead of 'auto &' substitution on const containers now works on arrays and pseudoarrays as well.
4. The error about multiple replacements in the same macro call is now documented in the tests (not solved though).
5. Due to [1], I had to add a dummy usage of the range element (like "(void) *It;" or similars) on the tests that had empty loops.
6. I removed the braces from the CHECK comments. I think that there is no need for them, and they confuse vim.
