Jonas Toth 9b127421b6 [clang-tidy] refactor bugprone-exception-escape analysis into class
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.

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.

Chandler Carruth 469bdefd44 Install new LLVM license structure and new developer policy.
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.

Jonas Toth 6a9f831ffd [clang-tidy] Fix case of local variables in modernize-use-nodiscard checker
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

```
---
Checks:          '
-clang-diagnostic-*,
readability-identifier-naming,
llvm-header-guard
'
WarningsAsErrors: ''
HeaderFilterRegex: ''
AnalyzeTemporaryDtors: false
FormatStyle:     LLVM
CheckOptions:
  - key:             readability-identifier-naming.IgnoreFailedSplit
    value:           '0'
  - key:             readability-identifier-naming.VariableCase
    value:           'CamelCase'
  - key:             readability-identifier-naming.LocalVariableCase
    value:           'CamelCase'
...

```

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.

Hyrum Wright 35cb7e9fe8 [clang-tidy] Add the abseil-duration-subtraction check
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.

Stephane Moore af4755aca8 [clang-tidy/checks] Update objc-property-declaration check to allow arbitrary acronyms and initialisms 🔧
Summary:
§1 Description

This changes the objc-property-declaration check to allow arbitrary acronyms and initialisms instead of using whitelisted acronyms. In Objective-C it is relatively common to use project prefixes in property names for the purposes of disambiguation. For example, the CIColor¹ and CGColor² properties on UIColor both represent symbol prefixes being used in proeprty names outside of Apple's accepted acronyms³. The union of Apple's accepted acronyms and all symbol prefixes that might be used for disambiguation in property declarations effectively allows for any arbitrary sequence of capital alphanumeric characters to be acceptable in property declarations. This change updates the check accordingly.

The test variants with custom configurations are deleted as part of this change because their configurations no longer impact behavior. The acronym configurations are currently preserved for backwards compatibility of check configuration.
