There was an inconsistency in formatting of delete expressions.
Before:
```
delete (void*)a;
delete[](void*) a;
```
After this patch:
```
delete (void*)a;
delete[] (void*)a;
```

- Add or remove empty lines surrounding union blocks.
- Fixes https://github.com/llvm/llvm-project/issues/53229, in which
keywords like class and struct in a line ending with left brace or
whose next line is left brace only, will be falsely recognized as
definition line, causing extra empty lines inserted surrounding blocks
with no need to be formatted.

The second space in `void foo() &` is always produced by clang-format,
and isn't evidence of any particular style.
Before this patch, it was considered evidence of PAS_Right, because
there is a space before a pointerlike ampersand.
This caused the following code to have "unstable" pointer alignment:
void a() &;
void b() &;
int *x;
PAS_Left, Derive=false would produce 'int* x' with other lines unchanged.
But subsequent formatting with Derive=true would produce 'int *x' again.

* Give I[1] and I[-1] a name:
- Easier to understand
- Easier to debug (since you don't go through operator[] everytime)
* TheLine->First != TheLine->Last follows since last is a l brace and
first isn't.
* Factor the check for is(tok::l_brace) out.
* Drop else after return.

This commit changes the condition of requiring comment to start with
alphanumeric characters to make no change only for a certain set of
characters, currently horizontal whitespace and punctuation characters,
to support wider set of leading characters unrelated to documentation
generation directives.

Fixes https://github.com/llvm/llvm-project/issues/31592.
This commits enables lexing of digraphs in C++11 and onwards.
Enabling them in C++03 is error-prone, as it would unconditionally treat sequences like "<:" as digraphs, even if they are followed by a single colon, e.g. "<::" would be treated as "[:" instead of "<" followed by "::". Lexing in C++11 doesn't have this problem as it looks ahead the following token.
The relevant excerpt from Lexer::LexTokenInternal:
```
// C++0x [lex.pptoken]p3:
// Otherwise, if the next three characters are <:: and the subsequent
// character is neither : nor >, the < is treated as a preprocessor
// token by itself and not as the first character of the alternative
// token <:.
```
Also, note that both clang and gcc turn on digraphs by default (-fdigraphs), so clang-format should match this behaviour.

This patch fixes the formatting of the code:

auto b = g([] {

which should be left as is, but before this patch was formatted to:

Before, the include sorter would break the code:
```
#include <stdio.h>
#include <stdint.h> /* long
comment */
```
and change it into:
```
#include <stdint.h> /* long
#include <stdio.h>

```
This commit handles only the most basic case of a single block comment on an include line, but does not try to handle all the possible edge cases with multiple comments.

Expected code:
```
/**/ //

```
was before misformatted to:
```
/**/ //

Because the "remaining length" (after the starting `/*`) of an empty block comment `/**/` was computed to be 0 instead of 2.

SortJavaScriptImports attempts to set its currently parsed token to an
invalid token when it reaches the end of the line. However in doing so,
it used a `FormatToken`, which contains a `Token Tok`. `Token` does not
have a constructor, so its fields start out as uninitialized memory.
`Token::startToken()` initializes all fields. Calling it in
`JavaScriptImportSorter`'s constructor thus fixes the problem.

Previously, these were unhandled and would terminate import sorting.
With this change, aliases sort as their own group, coming last after all
other imports.
Aliases are not sorted within their group, as they may reference each
other, so order is significant.
This reverts commit f750c3d95a. It fixes

Fixes https://github.com/llvm/llvm-project/issues/53430.
Initially, I had a quick and dirty approach, but it led to a myriad of special cases handling comments (that may add unwrapped lines).
So I added TT_RecordLBrace type annotations and it seems like a much nicer solution.
I think that in the future it will allow us to clean up some convoluted code that detects records.

- Fixes https://github.com/llvm/llvm-project/issues/53227 that wrongly
indents multiline comments
- Fixes wrong detection of single-line opening braces when used along
with those only opening scopes, causing crashes due to duplicated
replacements on the same token:
void foo()
{
{
int x;
}
}
- Fixes wrong recognition of first line of definition when the line
starts with block comment, causing crashes due to duplicated
replacements on the same token for this leads toward skipping the line
starting with inline block comment:
/*
Some descriptions about function
*/
/*inline*/ void bar() {
}
- Fixes wrong recognition of enum when used as a type name rather than
starting definition block, causing crashes due to duplicated
replacements on the same token since both actions for enum and for
definition blocks were taken place:
void foobar(const enum EnumType e) {
}
- Change to use function keyword for JavaScript instead of comparing
strings
- Resolves formatting conflict with options EmptyLineAfterAccessModifier
and EmptyLineBeforeAccessModifier (prompts with --dry-run (-n) or
--output-replacement-xml but no observable change)
- Recognize long (len>=5) uppercased name taking a single line as return
type and fix the problem of adding newline below it, with adding new
token type FunctionLikeOrFreestandingMacro and marking tokens in
UnwrappedLineParser:
void

return;
}
TYPENAME
func(int x, int y) {
// ...

- Remove redundant and repeated initialization
- Do no change to newlines before EOF
