[clang-format] Add BreakFunctionDefinitionParameters option (#84988)
This adds an option to break function definition parameters, putting
them on the next line after the function's opening paren.

This was a missing step towards allowing styles which require all
function definition parameters be on their own lines.

This implements the annotation of the values in TableGen.
The main changes are,

- modified consumeToken() to parseTableGenValue in 'if', 'assert' and
after '='.
- modified parseParens() to call parseTableGenValue inside.
- modified parseSquare() to to call parseTableGenValue inside, with

- modified parseAngle() to call parseTableGenValue inside, with skipping
separator tokens.

[ClangFormat] Fix formatting bugs. (#76245)
1. There are multiple calls to addFakeParenthesis; move the guard to not
   assign fake parenthesis into the function to make sure we cover all
   calls.
2. MustBreakBefore can be set on a token in two cases: either during
   unwrapped line parsing, or later, during token annotation. We must
   keep the latter, but reset the former.
3. Added a test to document that the intended behavior of preferring not
   to break between a return type and a function identifier.
   For example, with MOCK_METHOD(r, n, a)=r n a, the code
   MOCK_METHOD(void, f, (int a, int b)) should prefer the same breaks as
   the expanded void f(int a, int b).

ddc80637cc [clang-format] Break long string literals in C#, etc.
Now strings that are too long for one line in C#, Java, JavaScript, and
Verilog get broken into several lines.  C# and JavaScript interpolated
strings are not broken.

A new subclass BreakableStringLiteralUsingOperators is used to handle
the logic for adding plus signs and commas.  The updateAfterBroken
method was added because now parentheses or braces may be required after
the parentheses or commas are added.  In order to decide whether the
added plus sign should be unindented in the BreakableToken object, the
logic for it is taken out into a separate function
shouldUnindentNextOperator.

The logic for finding the continuation indentation when the option
AlignAfterOpenBracket is set to DontAlign is not implemented yet.  So in
that case the new line may have the wrong indentation, and the parts may
have the wrong length if the string needs to be broken more than once
because finding where to break the string depends on where the string
starts.

The preambles for the C# and Java unit tests are changed to the newer
style in order to allow the 3-argument verifyFormat macro.  Some cases
are changed from verifyFormat to verifyImcompleteFormat because those
use incomplete code and the new verifyFormat function checks that the
code is complete.

The line in the doc was changed to being indented by 4 spaces, that is,
the default continuation indentation.  It has always been the case.  It
was probably a mistake that the doc showed 2 spaces previously.

This commit was fist committed as 16ccba51072b.  The tests caused
assertion failures.  Then it was reverted in 547bce36132a.

369e8762b4 [clang-format] Stop comment disrupting indentation of Verilog ports
Before:

```
module x
    #( //
        parameter x)
    ( //
        input y);
endmodule
```

After:

```
module x
    #(//
      parameter x)
    (//
     input y);
endmodule
```

If the first line in a port or parameter list is not a comment, the
following lines will be aligned to the first line as intended:

```
module x
    #(parameter x1,
      parameter x2)
    (input y,
     input y2);
endmodule
```

Previously, the indentation would be changed to an extra continuation
indentation relative to the start of the parenthesis or the hash if
the first token inside the parentheses was a comment.  It is a feature
introduced in ddaa9be97839.  The feature enabled one to insert a `//`
comment right after an opening parentheses to put the function
arguments on a new line with a small indentation regardless of how
long the function name is, like this:

```
someFunction(anotherFunction( // Force break.
    parameter));
```

People are unlikely to use this feature in a Verilog port list because
the formatter already puts the port list on its own lines.  A comment
at the start of a port list is probably a comment for the port on the
next line.

We also removed the space before the comment so that its indentation
would be same as that for a line comment anywhere else in the port
list.

82a90caa88 [clang-format] Correctly format goto labels followed by blocks
There doesn't seem to be an issue on GitHub.  But previously, a space
would be inserted before the goto colon in the code below.

    switch (x) {
    case 0:
    goto_0: {
      action();
      break;
    }
    }

Previously, the colon following a goto label would be annotated as
`TT_InheritanceColon`.  A goto label followed by an opening brace
wasn't recognized.  It is easy to add another line to have
`spaceRequiredBefore` function recognize the case, but I believed it
is more proper to avoid doing the same thing in `UnwrappedLineParser`
and `TokenAnnotator`.  So now the label colons would be labeled in
`UnwrappedLineParser`, and `spaceRequiredBefore` would rely on that.

Previously we had the type `TT_GotoLabelColon` intended for both goto
labels and case labels.  But since handling of goto labels and case
labels differ somewhat, I split it into separate types for goto and
case labels.

This patch doesn't change the behavior for case labels.  I added the
lines annotating case labels because they would previously be
mistakenly annotated as `TT_InheritanceColon` just like goto labels.
And since I added the annotations, the checks for the `case` and
`default` keywords in `spaceRequiredBefore` are not necessary anymore.
