Angel Garcia Gomez b9f3059509 Use better mocks in modernize-make-unique, and fix matcher.
Summary: Add the second template argument to the unique_ptr mock, and update the matcher so that it only matches against cases where the second argument is the default.

Angel Garcia Gomez 199e5232b3 Document a bug in loop-convert and fix one of its subcases.
Summary: Now that we prioritize copying trivial types over using const-references where possible, I found some cases where, after the transformation, the loop was using the address of the local copy instead of the original object.

Angel Garcia Gomez c50b9fbb84 Fix bug in modernize-use-nullptr.
Summary:
https://llvm.org/bugs/show_bug.cgi?id=24960

modernize-use-nullptr would hit an assertion in some cases involving macros and initializer lists, due to finding a node with more than one parent (the two forms of the initializer list).

However, this doesn't mean that the replacement is incorrect, so instead of just rejecting this case I tried to find a way to make it work. Looking at the semantic form of the InitListExpr made sense to me (looking at both forms results in false negatives) but I am not sure of the things that we can miss by skipping the syntactic form.

Alexander Kornienko 30c423b1e3 [clang-tidy] Implement FixitHints for identifier references in IdentifierNamingCheck
This diff requires http://reviews.llvm.org/D13079 to be applied first. I wasn't sure about how to make patch series in Phabricator, and I wanted to keep the two separate for clarity.

It looks like that most cases can be supported with this patch. I'm not totally sure about the actual coverage though. I think that the matchers are very generic, but I'm still not totally fluent with the AST.

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.

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.
