Do not remove braces if the conditional of if/for/while might not
fit on a single line even after the opening brace is removed.
Examples:
// ColumnLimit: 20
// 45678901234567890
if (a) { /* Remove. */
foo();
}
if (-b >= c) { // Keep.
bar();
}

We have autogenerated pragma regions in our code
which where awkwardly broken up like this:
```
#pragma region foo(bar : hello)
```
becomes
```
#pragma region foo(bar \
: hello)
```
This fixes the problem by adding region as a keyword
and handling it the same way as pragma mark

The combination of
- AlignConsecutiveAssignments.Enabled = true
- BinPackArguments = false
would result in the first continuation line of a braced-init-list being
improperly indented (missing a shift) when in a continued function call.
Indentation was also wrong for braced-init-lists continuing a
direct-list-initialization. Check for opening braced lists in
continuation and ensure that the correct shift occurs.

Fixes https://github.com/llvm/llvm-project/issues/55407.
Given configuration:
```
UseTab: Always
PointerAlignment: Right
AlignConsecutiveDeclarations: true
```
Before, the pointer was misaligned in this code:
```
void f() {
unsigned long long big;
char *ptr; // misaligned
int i;
}
```
That was due to the fact that when handling right-aligned pointers, the Spaces were changed but StartOfTokenColumn was not.
Also, a tab was used not only for indentation but for spacing too when using `UseTab: ForIndentation` config option:
```
void f() {
unsigned long long big;
char *ptr; // \t after char
int i;
}
```

Due to how parseBracedList always stopped on the first closing angle
bracket and was used in parsing angle bracketed expression inside concept
definition, nested brackets inside concepts were parsed incorrectly.
nextToken() call before calling parseBracedList is required because
we were processing opening angle bracket inside parseBracedList second
time leading to incorrect logic after my fix.

This fixes regression introduced in 5e5efd8a91.
Before the culprit commit, macros in WhitespaceSensitiveMacros were correctly formatted even if their closing parenthesis weren't followed by semicolon (or, to be precise, when they were followed by a newline).
That commit changed the type of the macro token type from TT_UntouchableMacroFunc to TT_FunctionLikeOrFreestandingMacro.
Correct formatting (with `WhitespaceSensitiveMacros = ['FOO']`):
```
FOO(1+2)
FOO(1+2);
```
Regressed formatting:
```
FOO(1 + 2)
FOO(1+2);

Now a `-` or `+` following `;`, `sizeof`, `co_await`, or `delete` is
regarded as a unary operator.
Now a `*` or `&` following `case` is also a unary operator.

Fixes [[ https://github.com/llvm/llvm-project/issues/38995 | #38995 ]]
This is an attempt to modify the regular expression to identify
`@import` and `import` alongside the regular `#include`. The challenging
part was not to support `@` in addition to `#` but how to handle
everything that comes after the `include|import` keywords. Previously
everything that wasn't `"` or `<` was consumed. But as you can see in
this example from the issue #38995, there is no `"` or `<` following the
keyword:
```
@import Foundation;
```
I experimented with a lot of fancy and useful expressions in [this
online regex tool](https://regex101.com) only to find out that some
things are simply not supported by the regex implementation in LLVM.
* For example the beginning `[\t\ ]*` should be replacable by the
horizontal whitespace character `\h*` but this will break the
`SortIncludesTest.LeadingWhitespace` test.
That's why I've chosen to come back to the basic building blocks.
The essential change in this patch is the change from this regular
expression:
```
^[\t\ ]*#[\t\ ]*(import|include)[^"<]*(["<][^">]*[">])
~ ~~~~~~~~~~~~~~
^ ^
| |
only support # prefix not @ |
only support "" and <> as
delimiters
no support for C++ modules and ;
ending. Also this allows for ">
or <" or "" or <> which all seems
either off or wrong.
```
to this:
```
^[\t\ ]*[@#][\t\ ]*(import|include)([^"]*("[^"]+")|[^<]*(<[^>]+>)|[\t\
]*([^;]+;))
~~~~ ~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~
~~~~~~~~~~~~~~
^ ^ ^ ^ ^
| | | | |
Now support @ and #. Clearly support "" and <> as
well as an
include name without enclosing
characters.
Allows for no mixture of "> or
<" or
empty include names.
```
Here is how I've tested this patch:
```
ninja clang-Format
ninja FormatTests
./tools/clang/unittests/Format/FormatTests
--gtest_filter=SortIncludesTest*
```
And if that worked I doubled checked that nothing else broke by running
all format checks:
```
./tools/clang/unittests/Format/FormatTests
```
One side effect of this change is it should partially support
[C++20 Module](https://en.cppreference.com/w/cpp/language/modules)
`import` lines without the optional `export` in front. Adding
this can be a change on its own that shouldn't be too hard. I say
partially because the `@` or `#` are currently *NOT* optional in the
regular expression.
I see an opportunity to optimized the matching to exclude `@include` for
example. But eventually these should be caught by the compiler, so...
With my change, the matching group is not at a fixed position any
longer. I decided to
choose the last match (group) that is not empty.

Previously the import line would be unindented, looking like this.
```
for (const link of document.querySelectorAll("nav > a")) {
link.addEventListener("click", e => {
e.preventDefault();
import('/modules/my-module.js')
.then(module => {
module.loadPageInto(main);
