Alexander Kornienko 19bbeaf410 [clang-tidy] Disable google-readability-casting for .c files and their headers.
Some people have reasons to compile their .c files as C++ in some configurations
(e.g. for testing purposes), so just looking at LangOptions is not enough. This
patch disables the check on all .c files (and also for the headers included from
.c files).

Samuel Benzaquen aedd994560 Add flag --enable-check-profile to clang-tidy.
Summary:
Add flag --enable-check-profile to clang-tidy.
It turns on per-matcher profiles in MatchFinder and prints a report to
stderr at the end.

Alexander Kornienko d53d2686b3 Implemented clang-tidy configurability via .clang-tidy files.
Summary:
This adds a support for the .clang-tidy file reading using
FileOptionsProvider, -dump-config option, and changes tests to not depend on
default checks set.

Alexander Kornienko b3d331d18d Rename ChecksFilter to GlobList, as there's nothing specific to checks in it.
Summary:
Rename ChecksFilter to GlobList, as there's nothing specific to checks in it.
It's a rather generic way to represent sets of strings (or patterns), so it may
be used for something else in ClangTidy. The new name would not look strange
when used to filter other entities.

Alexander Kornienko a46952221e Allow per-file clang-tidy options.
Summary:
This patch makes it possible for clang-tidy clients to provide
different options for different translation units. The option, which doesn't
make sense to be file-dependent, was moved to a separate ClangTidyGlobalOptions
struct. Added parsing of ClangTidyOptions.

Alexander Kornienko 348cae8e2b Never filter-out compile errors in clang-tidy, display them as errors.
Summary:
No filters should affect the display of errors. Fixed a few tests,
which had compile errors.

We need to think what we should do with mapped errors (-Werror).

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 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.

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.
