Alexander Kornienko bef51cdf05 Improved llvm-namespace-comment check.
Summary:
Handle various forms of existing namespace closing comments, fix
existing comments with wrong namespace name, ignore short namespaces.

The state of this check now seems to be enough to enable it by default to gather
user feedback ;)

Alexander Kornienko 23fe95904c Change the behavior of clang-tidy -checks=, remove -disable-checks.
Summary:
Make checks filtering more intuitive and easy to use. Remove
-disable-checks and change the format of -checks= to a comma-separated list of
globs with optional '-' prefix to denote exclusion. The -checks= option is now
cumulative, so it modifies defaults, not overrides them. Each glob adds or
removes to the current set of checks, so the filter can be refined or overriden
by adding globs.

Example:
  The default value for -checks= is
  '*,-clang-analyzer-alpha*,-llvm-include-order,-llvm-namespace-comment,-google-*',
  which allows all checks except for the ones named clang-analyzer-alpha* and
  others specified with the leading '-'. To allow all google-* checks one can
  write:
    clang-tidy -checks=google-* ...
  If one needs only google-* checks, we first need to remove everything (-*):
    clang-tidy -checks=-*,google-*
  etc.

I'm not sure if we need to change something here, so I didn't touch the docs
yet.

Alexander Kornienko 826b5adb6c Store Errors inside ClangTidyContext instead of just pointer to an external
array. This simplifies usage of ClangTidyContext a bit and seems to be more
consistent.

Alexander Kornienko 4aab579d07 Fix assertion in google-explicit-constructor check when the constructor is
defined in a macro.

Summary:
We shouldn't suggest replacements in macros anyway, as we can't see all
usages of the macro and ensure the replacement is safe for all of them.

Alexander Kornienko 09952d2d71 Post-filter clang-tidy diagnostic messages.
Summary:
This patch implements filtering of clang-tidy diagnostic messages by
the check name, so that "clang-tidy -checks=^llvm-" won't output any clang
warnings, for example. This is also helpful to run specific static-analyzer
checks: static analyzer always needs core checks to be enabled, but the user may
be interested only in the checks he asked for.

This patch also exposes warning option names for built-in diagnostics. We need
to have a namespace for these names to avoid collisions and to allow convenient
filtering, so I prefix them with "-W". I'm not sure it's the best thing to do,
and maybe "W" or "clang-diagnostic-" or something like this would be better.

Peter Collingbourne 35c3f61d74 Add an argument comment checker to clang-tidy.
This checks that parameters named in comments that appear before arguments in
function and constructor calls match the parameter name used in the callee's
declaration. For example:

void f(int x, int y);

void g() {
  f(/*y=*/0, /*z=*/0);
}

contains two violations of the policy, as the names 'x' and 'y' used in the
declaration do not match names 'y' and 'z' used at the call site.

I think there is significant value in being able to check/enforce this policy
as a way of guarding against accidental API misuse and silent breakages
caused by API changes.

Although this pattern appears somewhat frequently in the LLVM codebase,
this policy is not prescribed by the LLVM coding standards at the moment,
so it lives under 'misc'.

Ahmed Charles 6a2dc5c381 [C++11] Replace OwningPtr with std::unique_ptr.
This removes all references to OwningPtr, which should be fairly
undisruptive to out-of-tree projects since they are unlikely to use
clang-tools-extra as a library instead of a set of tools.

Chandler Carruth 85e6e87171 Run llvm/utils/sort_includes.py over the Clang tools code. This doesn't
always produce as pretty of results as it does in LLVM and Clang, but
I don't mind and the value of having a single canonical ordering is very
high IMO.

Manuel Klimek 814f9bd93a Make clang's static analyzer checks available through clang-tidy.
This is implemented in a way that the current static analyzer
architecture allows, in the future we might want to revisit this.

With this change static analyzer checks are available from clang-tidy
by specifying -checks=clang-analyzer-<name>.

This change also fixes the use of the compilation database to allow
clang-tidy to be used like any other clang tool.

Daniel Jasper d07c840e6a Initial architecture for clang-tidy.
This is the first version of a possible clang-tidy architecture. The
purpose of clang-tidy is to detect errors in adhering to common coding
patterns, e.g. described in the LLVM Coding Standards.

This is still heavily in flux.
