Introduce a new check to upgrade user code based on API changes in Googletest.
The check finds uses of old Googletest APIs with "case" in their name and replaces them with the new APIs named with "suite".

Summary:
§1 Description
This check finds function names in function declarations in Objective-C files that do not follow the naming pattern described in the Google Objective-C Style Guide. Function names should be in UpperCamelCase and functions that are not of static storage class should have an appropriate prefix as described in the Google Objective-C Style Guide. The function `main` is a notable exception. Function declarations in expansions in system headers are ignored.
Example conforming function definitions:
```
static bool IsPositive(int i) { return i > 0; }
static bool ABIsPositive(int i) { return i > 0; }
bool ABIsNegative(int i) { return i < 0; }
```
A fixit hint is generated for functions of static storage class but otherwise the check does not generate a fixit hint because an appropriate prefix for the function cannot be determined.
§2 Test Notes
* Verified clang-tidy tests pass successfully.
* Used check_clang_tidy.py to verify expected output of processing google-objc-function-naming.m

This is triggering on a pattern that's both too broad (const
std::string& members can be used safely) and too narrow (std::string is
not the only class with this problem). It has a very low true positive
rate, just remove it until we find a better solution for dangling string
references.

Summary:
This is a small check to avoid throwing objc exceptions.
In specific it will detect the usage of @throw statement and throw warning.

Summary:
This is a new checker for objc files in clang-tidy.
The new check finds global variable declarations in Objective-C files that are not follow the pattern of variable names in Google's Objective-C Style Guide.
All the global variables should follow the pattern of "g[A-Z].*" (variables) or "k[A-Z].*" (constants). The check will suggest a variable name that follows the pattern
if it can be inferred from the original name.

Created new module bugprone and placed the check in that.
Finds memset() calls with potential mistakes in their arguments.
Replaces and extends the existing google-runtime-memset-zero-length check.
Cases covered:
* Fill value is a character '0'. Integer 0 might have been intended.
* Fill value is out of char range and gets truncated.
* Byte count is zero. Potentially swapped with the fill value argument.

It also suggests a fix-it, taking the name from $USER. This will be made

If there's memset(x, y, 0) in the code it's most likely a mistake. The
checker suggests a fix-it to swap 'y' and '0'.
I think this has the potential to be promoted into a general clang warning
after some testing in clang-tidy.

Summary:
We still allow the escape hatch foo(int /*x*/) and also suggest this
in a fixit. This is more powerful than the corresponding cpplint.py check
it also flags functions with multiple arguments as naming all arguments is
recommended by the google style guide.

Those may be incompatible with C++11 and are unnecessary. We suggest
removing the template arguments when they match the types of the make_pair
arguments or replace it with std::pair and explicit template arguments when
not.

This is the first version of a possible clang-tidy architecture. The
purpose of clang-tidy is to detect errors in adhering to common coding
patterns, e.g. described in the LLVM Coding Standards.
This is still heavily in flux.
