Summary:
The check should ignore the main function, the program entry point.
It is not possible to use `std::array<>` for the `argv`.
The alternative is to use `char** argv`.

Summary:
The check `bugprone-exception-escape` does an AST-based analysis to determine
if a function might throw an exception and warns based on that information.
The analysis part is refactored into a standalone class similiar to
`ExprMutAnalyzer` that is generally useful.
I intent to use that class in a new check to automatically introduce `noexcept`
if possible.

The readability-else-after-return check should be smarter about cases where the
variable defined in the condition is used in the `else` branch. This patch makes
it just ignore such cases, but alternative solutions may be better (added a

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.

a stray single '\r' from one file. These are the last line ending issues
I can find in the files containing parts of LLVM's file headers.
llvm-svn: 351634
This installs the new developer policy and moves all of the license
files across all LLVM projects in the monorepo to the new license
structure. The remaining projects will be moved independently.
Note that I've left odd formatting and other idiosyncracies of the
legacy license structure text alone to make the diff easier to read.
Critically, note that we do not in any case *remove* the old license
notice or terms, as that remains necessary until we finish the
relicensing process.
I've updated a few license files that refer to the LLVM license to
instead simply refer generically to whatever license the LLVM project is
under, basically trying to minimize confusion.
This is really the culmination of so many people. Chris led the
community discussions, drafted the policy update and organized the
multi-year string of meeting between lawyers across the community to
figure out the strategy. Numerous lawyers at companies in the community
spent their time figuring out initial answers, and then the Foundation's
lawyer Heather Meeker has done *so* much to help refine and get us ready
here. I could keep going on, but I just want to make sure everyone
realizes what a huge community effort this has been from the begining.

Summary:
Correct the case of the local variables..
Rational:
I want to be able to run clang-tidy on new clang-tidy checker code prior to creating a review (to demonstrate we should dog food our own tools during development, not my suggestion but @Eugene.Zelenko)
To this end I am running the following in a script, prior to make a change.
```
tidy:
@for source in $$(git status -suno | grep ".cpp$$" | cut -c4-) ;\
do \
clang-tidy -quiet $$source -- $(TIDY_FLAGS);\
done
```
I then want to go through the checkers and see which checkers most closely match the review style of the reviewers
```

Unfortunately in doing so, I have identified that my previous review {D55433} it violates what looks like to be the convention of local variables being in CamelCase.
Sending this small review in the hope it can be corrected.

Summary:
The diagnostics from google-objc-function-naming check will be more
actionable if they provide a brief description of the requirements from
the Google Objective-C style guide. The more descriptive diagnostics may
help clarify that functions in the global namespace must have an
appropriate prefix followed by Pascal case (engineers working previously
with static functions might not immediately understand the different
requirements of static and non-static functions).

Verified against the clang-tidy tests.

Summary:
This check uses the context of a subtraction expression as well as knowledge
about the Abseil Time types, to infer the type of the second operand of some
subtraction expressions in Duration conversions. For example:
absl::ToDoubleSeconds(duration) - foo
can become
absl::ToDoubleSeconds(duration - absl::Seconds(foo))
This ensures that time calculations are done in the proper domain, and also
makes it easier to further deduce the types of the second operands to these
expressions.

Summary:
Almost all code review comments on new checkers {D55433} {D48866} {D54349} seem to ask for the release notes to be added alphabetically, plus I've seen commits by @Eugene.Zelenko reordering the lists
Make add_new_check.py add those release notes alphabetically based on checker name
If include-fixer section is seen add it at the end
Minor change in the message format to prevent double newlines added before the checker.
Do the tools themselves have unit tests? (sorry new to this game)
- Tested adding new checker at the beginning
- Tested on adding new checker in the middle
- Tested on empty ReleasesNotes.rst (as we would see after RC)
