Daniel Jasper 9fe55a32b7 misc-unused-parameters: Don't warn on ParmVarDecls in the return type.
As there don't seem to be a good way of formulating a matcher that
finds all pairs of functions and their ParmVarDecls, just match on
functionDecls and iterate over their parameters. This should also be
more efficient as some checks are only performed once per function.

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.

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.
