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.

Daniel Jasper 3b6018b9f6 clang-tidy: Add initial check for "Don't use else after return".
As per the LLVM coding standards:
http://llvm.org/docs/CodingStandards.html#don-t-use-else-after-a-return

Initial version, probably still quite a bit to do until this is really
useful.

This is needed to avoid applying wrong fixes if Clang fails to recover from
