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 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.

Benjamin Kramer 6be414da26 [clang-tidy] Add a checker that warns on TODO comments without username.
It also suggests a fix-it, taking the name from $USER. This will be made

Benjamin Kramer ebab1500e0 [clang-tidy] Add a checker for zero-length memset.
If there's memset(x, y, 0) in the code it's most likely a mistake. The
checker suggests a fix-it to swap 'y' and '0'.

I think this has the potential to be promoted into a general clang warning
after some testing in clang-tidy.

Benjamin Kramer 14d42d9d1e [clang-tidy] Add a checker that flags unnamed parameters.
Summary:
We still allow the escape hatch foo(int /*x*/) and also suggest this
in a fixit. This is more powerful than the corresponding cpplint.py check
it also flags functions with multiple arguments as naming all arguments is
recommended by the google style guide.

Those may be incompatible with C++11 and are unnecessary. We suggest
removing the template arguments when they match the types of the make_pair
arguments or replace it with std::pair and explicit template arguments when
not.

Alexander Kornienko 276fc642d3 Another attempt to add a clang-tidy check for flagging C-style casts.
Summary:
The first version failed the SubstNonTypeTempateParmExpr-related test
on some buildbots. This one uses the new substNonTypeTempateParmExpr matcher to
filter out implicit C-style casts.

This patch depends on D4327.

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.

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.
