Aaron Ballman f4490cab0d Expand the simplify boolean expression check to handle implicit conversion of integral types to bool and improve the handling of implicit conversion of member pointers to bool.
Implicit conversion of member pointers are replaced with explicit comparisons to nullptr.

Implicit conversions of integral types are replaced with explicit comparisons to 0.

Alexander Kornienko dcbe5a9d17 [clang-tidy] Fix a false positive in google-runtime-memset
google-runtime-memset no longer issues a warning if the fill char value
is known to be an invalid fill char count.

Namely, it no longer warns for these:

  memset(p, 0, 0);
  memset(p, -1, 0);

In both cases, swapping the last two args would either be useless (there is
no actual bug) or wrong (it would introduce a bug).

Alexander Kornienko b959f4c338 [clang-tidy] Add UnnecessaryCopyInitialization check to new "performance" module in ClangTidy
Summary:
The patch adds a new ClangTidy check that detects when expensive-to-copy types are unnecessarily copy initialized from a const reference that has the same or are larger scope than the copy.

It currently only detects this when the copied variable is const qualified. But this will be extended to non const variables if they are only used in a const fashion.

Matthias Gehre 37f10a0c25 [clang-tidy] add check cppcoreguidelines-pro-bounds-constant-array-index
Summary:
This is http://reviews.llvm.org/D13746 but instead of including <array>,
a stub is provided.
This check flags all array subscriptions on static arrays and
std::arrays that either have a non-compile-time-constant index or are
out of bounds.

Dynamic accesses into arrays are difficult for both tools and humans to
validate as safe. array_view is a bounds-checked, safe type for
accessing arrays of data. at() is another alternative that ensures
single accesses are bounds-checked. If iterators are needed to access an
array, use the iterators from an array_view constructed over the array.

This rule is part of the "Bounds safety" profile of the C++ Core
Guidelines, see
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-bounds2-only-index-into-arrays-using-constant-expressions
