Summary:
Leave only -help, -version and options from the specified category.
Updated clang-check and clang-tidy. As clang-tidy is in a separate repository,
here's the diff:

// This file implements the CommonOptionsParser class used to parse common
|
|
// command-line options for clang tools, so that they can be run as separate
|
|
// command-line applications with a consistent common interface for handling
|
|
// compilation database and input files.
|
|
//
|
|
// It provides a common subset of command-line options, common algorithm
|
|
// for locating a compilation database and source files, and help messages
|
|
// for the basic command-line interface.
|
|
//
|
|
// It creates a CompilationDatabase and reads common command-line options.
|
|
//
|
|
// This class uses the Clang Tooling infrastructure, see
|
|
// http://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
|
|
// for details on setting it up with LLVM source tree.
