[clang-tidy] Fix crashes on `if consteval` in readability checks
The `readability-braces-around-statements` check tries to look at the
closing parens of the if condition to determine where to insert braces,
however, "consteval if" statements don't have a condition, and always
have braces regardless, so the skip can be checked.

The `readability-simplify-boolean-expr` check looks at the condition
of the if statement to determine what could be simplified, but as
"consteval if" statements do not have a condition that could be
simplified, they can also be skipped here.

There may still be more checks that try to look at the conditions of
`if`s that aren't included here

mydeveloperday fe866327c1 [clang-tidy] [PR50069] readability-braces-around-statements doesn't work well with [[likely]] [[unlikely]]
https://bugs.llvm.org/show_bug.cgi?id=50069

When clang-tidy sees:

```
if (true) [[unlikely]] {
    ...
}
```

It thinks the braces are missing and add them again.

```
if (true)  { [[unlikely]] {
    ...
  }
}
```

This revision aims to prevent that incorrect code generation

Nathan f9c46229e4 [clang-tidy] Disable Checks on If constexpr statements in template Instantiations for BugproneBranchClone and ReadabilityBracesAroundStatements
Summary: fixes [[ https://bugs.llvm.org/show_bug.cgi?id=32203 | readability-braces-around-statements broken for if constexpr]] and [[ https://bugs.llvm.org/show_bug.cgi?id=44229 | bugprone-branch-clone false positive with template functions and constexpr ]] by disabling the relevant checks on if constexpr statements while inside an instantiated template. This is due to how the else branch of an if constexpr statement is folded away to a null statement if the condition evaluates to false

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.

Alexander Kornienko a0ddf5fc1c [clang-tidy] readability-braces-around-statements false positive with char literals
Summary:
Single-line if statements cause a false positive when the last token in the conditional statement is a char constant:

```
if (condition)
  return 'a';
```

For some reason `findEndLocation` seems to skips too many (vertical) whitespaces in this case. The same problem already occured with string literals (https://reviews.llvm.org/D25558), and was fixed by adding a special check for this very case. I just extended the condition to also include char constants. No idea what really causes the issue though.

Summary:
Some of the misc checks belong to readability/. I'm moving them there
without changing check names for now. As the next step, I want to register some
of these checks in the google and llvm modules with suitable settings (e.g.
BracesAroundStatementsCheck). I'm not sure if we want to create a "readability"
module, probably not.
