Alexander Kornienko 1ca3b83255 [clang-tidy] Assert related checkers
This patch contains two assert related checkers. These checkers are the part of
those that is being open sourced by Ericsson
(http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-December/040520.html).

The checkers:

AssertSideEffect:
/// \brief Finds \c assert() with side effect.
///
/// The conition of \c assert() is evaluated only in debug builds so a condition
/// with side effect can cause different behaviour in debug / relesase builds.

StaticAssert:
/// \brief Replaces \c assert() with \c static_assert() if the condition is 
/// evaluatable at compile time.
///
/// The condition of \c static_assert() is evaluated at compile time which is
/// safer and more efficient.

Alexander Kornienko dd836f238d [clang-tidy] Various improvements in misc-use-override
* Better error message when more than one of 'virtual', 'override' and 'final'
    is present ("X is/are redundant since the function is already declared Y").
  * Convert the messages to the style used in Clang diagnostics: lower case
    initial letter, no trailing period.
  * Don't run the check for files compiled in pre-C++11 mode
    (http://llvm.org/PR22638).

Gabor Horvath d4637fb433 [clang-tidy] Checker for inaccurate use of erase() method.
Algorithms like remove() does not actually remove any element from the
container but returns an iterator to the first redundant element at the end
of the container. These redundant elements must be removed using the
erase() method. This check warns when not all of the elements will be
removed due to using an inappropriate overload.

Summary:
This makes clang-tidy merge the default set of checks with the one
provided in the configuration file instead of just using the checks from the
config file. This adds a way to modify the default set of checks while the
previous behavior required to always define the set of checks completely.

Alexander Kornienko e94b7c24c8 [clang-tidy] Use shrink_to_fit instead of copy and swap trick
The shrink_to_fit() method is more readable and more effective than
the copy and swap trick to reduce the capacity of a shrinkable container.
Note that, the shrink_to_fit() method is only available in C++11 and up.

Example:

std::vector<int>(v).swap(v); will be replaced with v.shrink_to_fit();

Alexander Kornienko 4babd689f9 clang-tidy: 'size' call that could be replaced with 'empty' on STL containers
We are porting some of the checkers at a company we developed to the Clang Tidy
infrastructure. We would like to open source the checkers that may be useful
for the community as well. This patch is the first checker that is being ported
to Clang Tidy. We also added fix-it hints, and applied them to LLVM:
http://reviews.llvm.org/D6924

The code compiled and the unit tests are passed after the fixits was applied.

The documentation of the checker:

/// The emptiness of a container should be checked using the empty method
/// instead of the size method. It is not guaranteed that size is a
/// constant-time function, and it is generally more efficient and also shows
/// clearer intent to use empty. Furthermore some containers may implement the
/// empty method but not implement the size method. Using empty whenever
/// possible makes it easier to switch to another container in the future.

It also uses some custom ASTMatchers. In case you find them useful I can submit
them as separate patches to clang. I will apply your suggestions to this patch.
