Eric Fiselier a2a6f85366 [clang-tidy]: Google: new check 'google-upgrade-googletest-case'
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".

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Stephane Moore e34a761d5b [clang-tidy/checks] Implement a clang-tidy check to verify Google Objective-C function naming conventions 📜
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

Haojian Wu 5529a244e1 Add new check in google module for Objective-C code to ensure global variables follow the naming convention of Google Objective-C Style Guide
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.

Alexander Kornienko 1efc425551 [clang-tidy] Default options in modules.
Summary:
This patch allows modules to specify default options for the checks
defined in them. This way a sufficiently configurable check can be registered in
multiple modules with different default options. E.g. the SpacesBeforeComments
option may be set to 1 for the "llvm-namespace-comments" check and to 2 for the
"google-readability-namespace-comment" check without modifying or extending the
check code.

This patch also registers the google-readability-braces-around-statements check
with suitable defaults.
