Summary:
This patch extends the already existing facility to add 'const' to variables
to be more flexible and correct. The previous version did not consider pointers
as value AND pointee. For future automatic introduction for const-correctness
this shortcoming needs to be fixed.
It always allows configuration where the 'const' token is inserted, either on
the left side (if possible) or the right side.
It adds many unit-tests to the utility-function that did not exist before, as
the function was implicitly tested through clang-tidy checks. These
tests were not changed, as the API is still compatible.

Adds a new ASTMatcher condition called 'hasInitStatement()' that matches if,
switch and range-for statements with an initializer. Reworked clang-tidy
readability-else-after-return to handle variables in the if condition or init
statements in c++17 ifs. Also checks if removing the else would affect object
lifetimes in the else branch.
Fixes PR44364.
Replace tidy::utils::lexer::getConstQualifyingToken with a corrected and also

Use LLVM_LINK_COMPONENTS to link the FrontendOpenMP library

This represents largely a full re-write of modernize-avoid-bind, adding
significant new functionality in the process. In particular:
* Both boost::bind and std::bind are now supported
* Function objects are supported in addition to functions
* Member functions are supported
* Nested calls are supported using capture-init syntax
* std::ref() and boost::ref() are now recognized, and will capture by reference.
* Rather than capturing with a global =, we now build up an individual
capture list that is both necessary and sufficient for the call.
* Fixits are supported in a much larger variety of scenarios than before.
All previous tests pass under the re-write, but a large number of new
tests have been added as well.

Breaks at least these tests on Windows:

Fix the confusing naming of `CompilerInstance::ModuleManager`. This is
actually an instance of `ASTReader`, which contains an instance of
`ModuleManager`. I have to assume there was a point in the past where
they were just one class, but it's been pretty confusing for a while. I
think it's time to fix it.
The new name is `TheASTReader`; the annoying `The` prefix is so that we
don't shadow the `ASTReader` class. I tried out `ASTRdr` but that
seemed less clear, and this choice matches `ThePCHContainerOperations`
just a couple of declarations below.
Also rename `CompilerInstance::getModuleManager` and
`CompilerInstance::createModuleManager` to `*ASTReader`, making some
cases of `getModuleManager().getModuleManager()` a little more clear.

Summary:
`modernize-use-equals-default` replaces default constructors/destructors with `= default;`. When the optional semicolon after a member function is present, this results in two consecutive semicolons.
This patch checks to see if the next non-comment token after the code to be replaced is a semicolon, and if so offers a replacement of `= default` rather than `= default;`.
This patch adds trailing comments and semicolons to about 5 existing tests.

Summary:
readability-redundant-member-init removes redundant / unnecessary member and base class initialization. Unfortunately for the specific case of a copy constructor's initialization of a base class, gcc at strict warning levels warns if "base class is not initialized in the copy constructor of a derived class".
This patch adds an option `IgnoreBaseInCopyConstructors` defaulting to 0 (thus maintaining current behavior by default) to skip the specific case of removal of redundant base class initialization in the copy constructor. Enabling this option enables the resulting code to continue to compile successfully under `gcc -Werror=extra`. New test cases `WithCopyConstructor1` and `WithCopyConstructor2` in clang-tools-extra/test/clang-tidy/readability-redundant-member-init.cpp show that it removes redundant members even from copy constructors.

In addition to adding `override` wherever possible, clang-tidy's `modernize-use-override` nicely removes `virtual` when `override` or `final` is specified, and further removes override when final is specified. While this is great default behavior, when code needs to be compiled with gcc at high warning levels that include `gcc -Wsuggest-override` or `gcc -Werror=suggest-override`, clang-tidy's removal of the redundant `override` keyword causes gcc to emit a warning or error. This discrepancy / conflict has been noted by others including a comment on Stack Overflow and by Mozilla's Firefox developers.
This patch adds an AllowOverrideAndFinal option defaulting to 0 - thus preserving current behavior - that when enabled allows both `override` and `final` to co-exist, while still fixing all other issues.

Summary:
`readability-redundant-string-init` was one of several clang-tidy checks documented as failing for C++17. (The failure mode in C++17 is that it changes `std::string Name = ""`; to `std::string Name = Name;`, which actually compiles but crashes at run-time.)
Analyzing the AST with `clang -Xclang -ast-dump` showed that the outer `CXXConstructExprs` that previously held the correct SourceRange were being elided in C++17/2a, but the containing `VarDecl` expressions still had all the relevant information. So this patch changes the fix to get its source ranges from `VarDecl`.
It adds one test `std::string g = "u", h = "", i = "uuu", j = "", k;` to confirm proper warnings and fixit replacements in a single `DeclStmt` where some strings require replacement and others don't. The readability-redundant-string-init.cpp and readability-redundant-string-init-msvc.cpp tests now pass for C++11/14/17/2a.

entirely in favor of a simple type alias, deprecate `MatchConsumer` and change

Summary:
New checker called bugprone-not-null-terminated-result. This checker finds
function calls where it is possible to cause a not null-terminated result.
Usually the proper length of a string is `strlen(src) + 1` or equal length
of this expression, because the null terminator needs an extra space.
Without the null terminator it can result in undefined behaviour when the
string is read.
The following and their respective `wchar_t` based functions are checked:
`memcpy`, `memcpy_s`, `memchr`, `memmove`, `memmove_s`, `strerror_s`,
`strncmp`, `strxfrm`
The following is a real-world example where the programmer forgot to
increase the passed third argument, which is `size_t length`.
That is why the length of the allocated memory is not enough to hold the
null terminator.
```
static char *stringCpy(const std::string &str) {
char *result = reinterpret_cast<char *>(malloc(str.size()));
memcpy(result, str.data(), str.size());
return result;
}
```
In addition to issuing warnings, fix-it rewrites all the necessary code.
It also tries to adjust the capacity of the destination array:
```
static char *stringCpy(const std::string &str) {
char *result = reinterpret_cast<char *>(malloc(str.size() + 1));
strcpy(result, str.data());
return result;
}
```
Note: It cannot guarantee to rewrite every of the path-sensitive memory
allocations.

Summary:
Apple documentation states that:
"If two objects are equal, they must have the same hash value. This last
point is particularly important if you define isEqual: in a subclass and
intend to put instances of that subclass into a collection. Make sure
you also define hash in your subclass."
https://developer.apple.com/documentation/objectivec/1418956-nsobject/1418795-isequal?language=objc
In many or all versions of libobjc, -[NSObject isEqual:] is a pointer
equality check and -[NSObject hash] returns the messaged object's
pointer. A relatively common form of developer error is for a developer to
override -isEqual: in a subclass without overriding -hash to ensure that
hashes are equal for objects that are equal.
It is assumed that an override of -isEqual: is a strong signal for
changing the object's equality operator to something other than pointer
equality which implies that a missing override of -hash could result in
distinct objects being equal but having distinct hashes because they are
independent instances. This added check flags classes that override
-isEqual: but inherit NSObject's implementation of -hash to warn of the
potential for unexpected behavior.
The proper implementation of -hash is the responsibility of the
developer and the check will only verify that the developer made an
effort to properly implement -hash. Developers can set up unit tests
to verify that their implementation of -hash is appropriate.

Clang-tidy supports output diagnostics from header files if user

```
// a.h is in /src/a/a.h
// b.h is in /src/b/b.h
...
// c.cpp is in /src/c.cpp
```
Now, we set --header-filter as --header-filter=/a/. That means we only
want to check header files under /src/a/ path, and ignore header files
uder /src/b/ path, but in current implementation, clang-tidy will check
/src/b/b.h also, because the name of b.h used in clang-tidy is
/src/a/../b/b.h.
