Malcolm Parsons b744ce87fc [clang-tidy] Ignore default arguments in modernize-default-member-init
Summary:
Default member initializers cannot refer to constructor parameters, but modernize-default-member-init was trying to when the default constructor had default arguments.

Change the check to ignore default arguments to the default constructor.

Fixes PR31524.

Mads Ravn 72bcc049f2 [clang-tidy] Add check 'misc-string-compare'.
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)) {
  }
```

Alexander Kornienko ebdfb9cf0c [Clang-tidy] check for malloc, realloc and free calls
Summary:
This checker flags the use of C-style memory management functionality and notes about modern alternatives.
In an earlier revision it tried to autofix some kind of patterns, but that was a bad idea. Since memory management can be so widespread in a program, manual updating is most likely necessary.
Maybe for special cases, there could be later additions to this basic checker.

This is the first checker I wrote and I never did something with clang (only compiling programs). So whenever I missed conventions or did plain retarded stuff, feel free to point it out! I am willing to fix them and write a better checker.

I hope the patch does work, I never did this either. On a testapply in my repository it did, but I am pretty unconfident in my patching skills :)

Eric Fiselier 732a3e0dd1 [clang-tidy] Fix identifier naming for initializer list member initializers.
Summary:
This patch adds handling for member initializers in a constructors initializer list. Previously we only handled base-class and delegating initializers, which are transformed by the `TypeLoc` matcher. For Example:

```
// Style options: All identifiers should start with an upper case letter.
struct base { ...  }; 
struct der :  base {
  int field;  // FIXES: int Field;
  der() : der(42) {} // FIXES: Der() : Der(42) {}
  der(int X) : base(), field(X) {} // FIXES: Der(int X) : Base(), field(X)
  // Note that `field` doesn't get replaced
};
```
