Summary: using "auto" on a loop that iterates over ints is kind of an overkill. Use the real type name instead.

Summary:
This check flags all calls to c-style vararg functions and all use
of va_list, va_start and va_arg.
Passing to varargs assumes the correct type will be read. This is
fragile because it cannot generally be enforced to be safe in the
language and so relies on programmer discipline to get it right.
This rule is part of the "Type safety" profile of the C++ Core
Guidelines, see
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-type8-avoid-reading-from-varargs-or-passing-vararg-arguments-prefer-variadic-template-parameters-instead
This commits also reverts
"[clang-tidy] add cert's VariadicFunctionDefCheck as cppcoreguidelines-pro-type-vararg-def"
because that check makes the SFINAE use of vararg functions impossible.

Summary:
Add a check that replaces empty bodies of special member functions with '= default;'.
For now, it is only implemented for the default constructor and the destructor, which are the easier cases.
The copy-constructor and the copy-assignment operator cases will be implemented later.
I applied this check to the llvm code base and found 627 warnings (385 in llvm, 9 in compiler-rt, 220 in clang and 13 in clang-tools-extra).
Applying the fixes didn't break any build or test, it only caused a -Wpedantic warning in lib/Target/Mips/MipsOptionRecord.h:33 becaused it replaced
virtual ~MipsOptionRecord(){}; to virtual ~MipsOptionRecord()= default;;

Summary:
This check flags all access to members of unions. Passing unions as a
whole is not flagged.
Reading from a union member assumes that member was the last one
written, and writing to a union member assumes another member with a
nontrivial destructor had its destructor called. This is fragile because
it cannot generally be enforced to be safe in the language and so relies
on programmer discipline to get it right.

Summary:
This check flags all usage of pointer arithmetic, because it could lead
to an
invalid pointer.
Subtraction of two pointers is not flagged by this check.
Pointers should only refer to single objects, and pointer arithmetic is
fragile and easy to get wrong. array_view is a bounds-checked, safe type
for accessing arrays of data.
This rule is part of the "Bounds safety" profile of the C++ Core
Guidelines, see
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-bounds1-dont-use-pointer-arithmetic-use-array_view-instead

Summary:
This check flags all usages of static_cast, where a base class is casted
to a derived class.
In those cases, a fixit is provided to convert the cast to a
dynamic_cast.
Use of these casts can violate type safety and cause the program to
access a variable that is actually of type X to be accessed as if it
were of an unrelated type Z.
This rule is part of the "Type safety" profile of the C++ Core
Guidelines, see

Summary:
https://llvm.org/bugs/show_bug.cgi?id=24960
modernize-use-nullptr would hit an assertion in some cases involving macros and initializer lists, due to finding a node with more than one parent (the two forms of the initializer list).
However, this doesn't mean that the replacement is incorrect, so instead of just rejecting this case I tried to find a way to make it work. Looking at the semantic form of the InitListExpr made sense to me (looking at both forms results in false negatives) but I am not sure of the things that we can miss by skipping the syntactic form.
