We can no longer use MatchingParen of FormatToken as an indicator

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:

This adds command-line flags to the tool:
+ -print: prints changed source code
+ -print=changes: prints headers added/removed
+ -edit: rewrites code in place
+ -insert=0/-remove=0: disables additions/deletions for the above
These are supported by a couple of new functions dumped into Analysis:
analyze() sits on top of walkUsed and makes used/unused decisions for
Includes. fixIncludes() applies those results to source code.

Arbitrary lookahead restricts the implementation of our TokenSource,

Instead, use getNextToken to parse lookahead linearly, and

Declarations of operator overloads are annotated with

Ran into an issue where function declarations inside function
scopes or uses of sizeof inside a function would treat the && in

Attempt to fix this by assuming reference when followed by ',' or
')'. Also adds tests for these.
Also hit an edge case in another test that treated "and" the same

I've:
- Sorted the members of FormatStyle alphabetical. The enums and structs
are kept close to the member.
- Sorted the yaml io functions, based on the type they operate on.
- Sorted the initializers in getLLVMStyle(), except that penalities are
kept at the end.
- Sorted the io of FormatStyle, this changes the --dump-config behavior.
- Moved the deprecated options into the only input case, this also
changes --dump-config, it does not put the not directly used options
in the .clang-format anymore.
- Sorted the comparisons in operator==.
- Added WhiteSpaceMacros in operator==, I've not actively looked if all
other members are compared.
- This showed flawed tests (or in my opinion a flawed io operation, but
that is another discussion and change).

Before this patch code like this:

This patch changes the * to become a PointerOrReference instead

In our code-base we auto-generate pragma regions the regions
look like method signatures like:
`#pragma region MYREGION(Foo: bar)`
The problem here was that the rest of the line after region
was not marked as stringliteral as in the case of pragma mark
so clang-format tried to change the formatting based on the
method signature.
Added test and mark it similar as pragma mark.

Currently, we parse lines inside of a compiler `#pragma` the same way we
parse any other line. This is fine for some cases, like separating
expressions and adding proper spacing, but in others it causes some poor
results from miscategorizing some tokens.
For example, the OpenMP offloading uses certain clauses that contain
special characters like `map(tofrom : A[0:N])`. This will be formatted
poorly as it will be split between lines on the first colon.
Additionally the subscript notation will lead to poor spacing. This can
be seen in the OpenMP tests as the automatic clang formatting with
inevitably ruin the formatting.
For example, the following contrived example will be formatted poorly.
```
#pragma omp target teams distribute collapse(2) map(to: A[0 : M * K]) \
map(to: B[0:K * N]) map(tofrom:C[0:M*N]) firstprivate(Alpha) \
firstprivate(Beta) firstprivate(X) firstprivate(D) firstprivate(Y) \
firstprivate(E) firstprivate(Z) firstprivate(F)
```
This results in this when formatted, which is far from ideal.
```
#pragma omp target teams distribute collapse(2) map(to \
: A [0:M * K]) \
map(to \
: B [0:K * N]) map(tofrom \
: C [0:M * N]) firstprivate(Alpha) \
firstprivate(Beta) firstprivate(X) firstprivate(D) firstprivate(Y) \
firstprivate(E) firstprivate(Z) firstprivate(F)
```
This patch seeks to improve this by adding extra logic where the parsing goes
awry. This is primarily caused by the colon being parsed as an inline-asm
directive and the brackes an objective-C expressions. Also the line gets
indented every single time the line is dropped.
This doesn't implement true parsing handling for OpenMP statements.

Inside the arguments part of a function pointer declaration,
`determineStarAmpUsage` results in a binary operator rather than
pointers, because said parens are assumed to be an expression.
This patch correctly marks the argument parens of a function
pointer type as not an expression. Note that this fix already
existed for Objective-C blocks as part of f1f267b447.
As Objective-C blocks and C/C++ function pointers share a lot
of the same logic, that fix also makes sense here.

When a compound requirement is too long to fit onto a single line, the
braces are split apart onto separate lines, and the contained expression
is indented. However, this indentation would also apply to the closing
brace and the trailing return type requirement thereof.
This was because the indentation level was being restored after all
trailing things were already read
With this change, the initial level of the opening brace is set before
attempting to read any trailing return type requirements

Summary:
clang-format makes multiple passes when #if/#else preprocessor blocks are found. It will make
one pass for normal code and code in the #if block, and then it will make another pass for just
the code in #else blocks. This often results in invalid alignment inside the else blocks because
they do not have any scope or indentAndNestingLevel context from their surrounding tokens/lines.
This patch remedies that by caching any initial indentAndNestingLevel from a second pass and
not breaking/returning early when a scope change is detected.
