Alexander Kornienko f5e72b0448 [clang-tidy] Add readability-simplify-boolean-expr check to clang-tidy 
This check looks for comparisons between boolean expressions and boolean
constants and simplifies them to just use the appropriate boolean expression
directly.

if (b == true) becomes if (b)
if (b == false) becomes if (!b)
if (b && true) becomes if (b)
if (b && false) becomes if (false)
if (b || true) becomes if (true)
if (b || false) becomes if (b)
e ? true : false becomes e
e ? false : true becomes !e
if (true) t(); else f(); becomes t();
if (false) t(); else f(); becomes f();
if (e) return true; else return false; becomes return (e);
if (e) return false; else return true; becomes return !(e);
if (e) b = true; else b = false; becomes b = e;
if (e) b = false; else b = true; becomes b = !(e);

// Clang Tools repository
//===----------------------------------------------------------------------===//

Welcome to the repository of extra Clang Tools.  This repository holds tools
that are developed as part of the LLVM compiler infrastructure project and the
Clang frontend.  These tools are kept in a separate "extra" repository to
allow lighter weight checkouts of the core Clang codebase.

This repository is only intended to be checked out inside of a full LLVM+Clang
tree, and in the 'tools/extra' subdirectory of the Clang checkout.

All discussion regarding Clang, Clang-based tools, and code in this repository
should be held using the standard Clang mailing lists:
  http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev

Code review for this tree should take place on the standard Clang patch and
commit lists:
  http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits

If you find a bug in these tools, please file it in the LLVM bug tracker:
  http://llvm.org/bugs/
