Alexander Kornienko 8384d491d8 [clang-tidy] Refactor: Move readability checks to namespace clang::tidy::readability
clang-tidy checks are organized into modules. This refactoring moves the

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.

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.

Alexander Kornienko b23eb5e3f7 [clang-tidy] Move the missing namespace comment warnings to the closing brace
Summary:
The google-readability-namespace-comments/llvm-namespace-comment
warnings are quite confusing when they appear at the beginning of a long
namespace and the closing brace is not in sight.

For convenience added notes pointing to the start of the namespace.

Alexander Kornienko 1efc425551 [clang-tidy] Default options in modules.
Summary:
This patch allows modules to specify default options for the checks
defined in them. This way a sufficiently configurable check can be registered in
multiple modules with different default options. E.g. the SpacesBeforeComments
option may be set to 1 for the "llvm-namespace-comments" check and to 2 for the
"google-readability-namespace-comment" check without modifying or extending the
check code.

This patch also registers the google-readability-braces-around-statements check
with suitable defaults.

Alexander Kornienko 35ddae4a9b [clang-tidy] Move some of the misc checks to readability/
Summary:
Some of the misc checks belong to readability/. I'm moving them there
without changing check names for now. As the next step, I want to register some
of these checks in the google and llvm modules with suitable settings (e.g.
BracesAroundStatementsCheck). I'm not sure if we want to create a "readability"
module, probably not.

Alexander Kornienko 33fc3db9a1 Add NamespaceCommentCheck to the Google module.
Summary:
This uses a bit hacky way to set the defaults for the spaces before
comments, but it's also one of the simplest ways. Fixed a bug with how the
SpacesBeforeComments option was used.
