Summary:
This patch makes modernize-use-emplace remove unnecessary make_ calls from push_back calls and turn them into emplace_back -- the same way make_pair calls are handled.
Custom make_ calls can be removed for custom tuple-like types -- two new options that control that are `TupleTypes` and `TupleMakeFunctions`. By default, the check removes calls to `std::make_pair` and `std::make_tuple`.
Eq.
```
std::vector<std::tuple<int, char, bool>> v;
v.push_back(std::make_tuple(1, 'A', true)); // --> v.emplace_back(1, 'A', true);
```

Summary:
And also enable it by default to be consistent with e.g.
modernize-use-using.
This helps e.g. when running this check on cppunit client code where the
macro is provided by the system, so there is no easy way to modify it.

Summary:
When there is a push_back with a call to make_pair, turn it into emplace_back and remove the unnecessary make_pair call.
Eg.
```
std::vector<std::pair<int, int>> v;
v.push_back(std::make_pair(1, 2)); // --> v.emplace_back(1, 2);
```
make_pair doesn't get removed when explicit template parameters are provided, because of potential problems with type conversions.

This check will find occurrences of ``std::random_shuffle`` and replace it with ``std::shuffle``. In C++17 ``std::random_shuffle`` will no longer be available and thus we need to replace it.
Example of case that it fixes
```
std::vector<int> v;
// First example
std::random_shuffle(vec.begin(), vec.end());
```

Summary:
The "performance-inefficient-vector-operation" check finds vector oprations in
for-loop statements which may cause multiple memory reallocations.
This is the first version, only detects typical for-loop:
```
std::vector<int> v;
for (int i = 0; i < n; ++i) {
v.push_back(i);
}
// or
for (int i = 0; i < v2.size(); ++i) {
v.push_back(v2[i]);
}
```
We can extend it to handle more cases like for-range loop in the future.

Summary:
Hello everybody,
this is an incremental patch for the NoMalloc-Checker I wrote. It allows to configure the memory-management functions, that are checked,
This might be helpful for a code base with custom functions in use, or non-standard functionality, like posix_memalign.

Summary:
Add an option to function-size to warn about high parameter counts.
This might be relevant for cppcoreguidelines and the safety module as well. Since the safety module is not landed in master already, i did not create an alias, but that can be done later as well.

Summary:
Replaces explicit calls to the constructor in a return with a braced
initializer list. This way the return type is not needlessly duplicated in the
return type and the return statement.
```
Foo bar() {
Baz baz;
return Foo(baz);
}
// transforms to:
Foo bar() {
Baz baz;
return {baz};
}

I have a created a new check for clang tidy: misc-string-compare. This will check for incorrect usage of std::string::compare when used to check equality or inequality of string instead of the string equality or inequality operators.
Example:
```
std::string str1, str2;
if (str1.compare(str2)) {
}
```
