Alexander Kornienko 54461eb389 Improve clang-tidy diagnostic output and filtering.
Summary:
This patch introduces several improvements to clang-tidy diagnostic;
  1. Make filtering of messages from non-user code more reliable. Output an
     error when it or any of the related notes touches user code. This fixes an
     assertion when an error has a location in a system header, and one of the
     notes relates to user code.
  2. In order for 1. to work, subscribe to the static analyzer diagnostics using
     a custom PathDiagnosticConsumer.
  3. Enable colors on supported terminals.
  4. Output FixItHints.

Alp Toker a143676664 Fix another invalid getCustomDiagID() use to unbreak the build
It was calling the utility wrapper that now requires a constant string
following clang r200132. The StringRef version on DiagnosticIDs appears to have
been what was intended so change to that.

Alp Toker 82f8c50a73 Prospective build fix for unsafe usage of getCustomDiagID()
This now requires a compile-time constant string so let's build proper
diagnostic IDs and pass through the inputs as arguments.

Tracks clang changes in r200132.

Alexander Kornienko 41bfe8dde1 Add the check name to the clang-tidy diagnostic output.
Summary:
Pass check names all the way from ClangTidyModule through
ClangTidyCheck and ClangTidyContext to ClangTidyError, and output it in
handleErrors. This allows to find mis-behaving check and disable it easily.

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.

Let me know if you spot really serious problems here.

Alexander Kornienko 175fefbda3 Refactored Clang-tidy for better reusability.
Summary:
Made ClangTidyAction more slim and moved its declaration to header to
allow easy creation of Clang-tidy ASTConsumer. Don't derive from
clang::ento::AnalysisAction, use clang::ento::CreateAnalysisConsumer instead
(I'll propose making this function a part of a public API in a separate patch).

Use MultiplexConsumer instead of a custom class.

Don't re-filter checkers list for each TU.

Alexander Kornienko fb9e92b167 Clang-tidy: added --disable-checks, --list-checks options.
Summary:
Allow disabling checks by regex. By default, disable alpha.* checks,
that are not particularly good tested (e.g. IdempotentOperationChecker, see
http://llvm-reviews.chandlerc.com/D2427).

Fixed a bug, that would disable all analyzer checks, when using a regex more
strict, than 'clang-analyzer-', for example --checks='clang-analyzer-deadcode-'.

Added --list-checks to list all enabled checks. This is useful to test specific
values in --checks/--disable-checks.

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.
