These are all compiler built-in equivalents of the unary type traits
found in [[meta.trans]][1]. The compiler already has all of the
information it needs to answer these transformations, so we can skip
needing to make partial specialisations in standard library
implementations (we already do this for a lot of the query traits). This
will hopefully improve compile times, as we won't need use as much
memory in such a base part of the standard library.

These statements are like switch statements in C, but without the 'case'
keyword in labels.
How labels are parsed. In UnwrappedLineParser, the program tries to
parse a statement every time it sees a colon. In TokenAnnotator, a
colon that isn't part of an expression is annotated as a label.
The token type `TT_GotoLabelColon` is added. We did not include Verilog
in the name because we thought we would eventually have to fix the
problem that case labels in C can't contain ternary conditional
expressions and we would use that token type.
The style is like below. Labels are on separate lines and indented by
default. The linked style guide also has examples where labels and the
corresponding statements are on the same lines. They are not supported
for now.

Now things inside hierarchies like modules and interfaces are
indented. When the module header spans multiple lines, all except the
first line are indented as continuations. We added the property
`IsContinuation` to mark lines that should be indented this way.
In order that the colons inside square brackets don't get labeled as
`TT_ObjCMethodExpr`, we added a check to only use this type when the
language is not Verilog.

Some tests are moved into FormatTestVerilog.Block from

Verilog uses the backtick instead of the hash. In this revision
backticks are lexed manually and then get labeled as hashes so the logic
for handling C preprocessor stuff don't have to change. Hashes get
labeled as identifiers for Verilog-specific stuff like delays.

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 \

This fixes the problem by adding region as a keyword
and handling it the same way as pragma mark

There was some duplicate code in determineStarAmpUsage and

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.

We have a little problem. TokenAnnotator::resetTokenMetadata() resets
the type, except for a (growing) whitelist. This is because the
TokenAnnotator visits some tokens multiple times. E.g. trying to
identify if a < is an operator less or a template opener. And in some
runs, which are bascially "reverted" the types are reset.
On the other hand, if the parser does already know the type, it should
be able to set it, without it being reset. So we introduce the ability
to set a type and make that final.

Fixes https://github.com/llvm/llvm-project/issues/53876.
This is a solution for standard C++ casts: const_cast, dynamic_cast, reinterpret_cast, static_cast.
A general approach handling all possible casts is not possible without semantic information.
Consider the code:
```
static_cast<T>(*function_pointer_variable)(arguments);
```
vs.
```
some_return_type<T> (*function_pointer_variable)(parameters);
// Later used as:
function_pointer_variable = &some_function;
return function_pointer_variable(args);
```
In the latter case, it's not a cast but a variable declaration of a pointer to function.
Without knowing what `some_return_type<T>` is (and clang-format does not know it), it's hard to distinguish between the two cases. Theoretically, one could check whether "parameters" are types (not a cast) and "arguments" are value/expressions (a cast), but that might be inefficient (needs lots of lookahead).
