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.

[clang-tidy] Avoid C arrays check

Summary:
[[ https://bugs.llvm.org/show_bug.cgi?id=39224 | PR39224 ]]
As discussed, we can't always do the transform automatically due to that array-to-pointer decay of C array.
In order to detect whether we can do said transform, we'd need to be able to see all usages of said array,
which is, i would say, rather impossible if e.g. it is in the header.
Thus right now no fixit exists.

Exceptions: `extern "C"` code.

[clang-tidy] Add modernize-concat-nested-namespaces check

Summary:
Finds instances of namespaces concatenated using explicit syntax, such as `namespace a { namespace b { [...] }}` and offers fix to glue it to `namespace a::b { [...] }`.

Properly handles `inline` and unnamed namespaces. ~~Also, detects empty blocks in nested namespaces and offers to remove them.~~

Test with common use cases included.
I ran the check against entire llvm repository. Except for expected `nested namespace definitions only available with -std=c++17 or -std=gnu++17` warnings I noticed no issues when the check was performed.

Example:
```
namespace a { namespace b {
void test();
}}

```
can become
```
namespace a::b {
void test();
}
```

Summary:
New checker to replace dynamic exception
specifications

This is an alternative to D18575 which relied on reparsing the decl to
find the location of dynamic exception specifications, but couldn't
deal with preprocessor conditionals correctly without reparsing the
entire file.

This approach uses D20428 to find dynamic exception specification
locations and handles all cases correctly.

[clang-tidy] New check: modernize-replace-random-shuffle.

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;

std::random_shuffle(vec.begin(), vec.end());
