This reverts commit 879bfe6a979295f834b76df66b19a203b93eed0f.
owenpan@ pointed out on https://reviews.llvm.org/D140956 that this
actually makes the formatting more consistent, so it's not a regression.
This patch properly recognizes the generic selection expression
introduced in C11, by adding an additional token type for the colons
present in such expressions.
Previously, they would be recognized as
"inline ASM colons" purely by the fact that those are the last thing
checked for.
I tried to avoid adding an addition token type, but since colons by
default like having spaces around them, I chose to add a new type so
that no space is added after the type selector.
Currently, no aspect of the formatting of these expressions in able to
be configured, as I'm not sure what could even be configured here.
One notable thing is that association list is always formatted as
either entirely on one line, if it can fit, or with line breaks
after every comma in the expression (also after the controlling expr.)
This visually makes them more similar to switch statements when long,
matching the behaviour of the selection expression, being that of a sort
of switch on types, but also allows for terseness when only selecting
for a few things.

It appears that this regresses some function definitions, added an
example as a comment over at https://reviews.llvm.org/D140956.
The BracketAlignmentStyle BAS_BlockIndent was forcing breaks before a
closing right parenthesis yielding strange-looking results in case of
code structures that have a left parens immediately following a right
parens ")(" such as is seen with indirect function calls via function
pointers and with type casting.

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:

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.

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.

This style is similar to AlwaysBreak, but places closing brackets on new lines.
For example, if you have a multiline parameter list, clang-format currently only supports breaking per-parameter, but places the closing bracket on the line of the last parameter.
Function(
param1,
param2,
param3);
A style supported by other code styling tools (e.g. rustfmt) is to allow the closing brackets to be placed on their own line, aiding the user in being able to quickly infer the bounds of the block of code.
Function(
param1,
param2,
param3
);
For prior work on a similar feature, see: https://reviews.llvm.org/D33029.
Note: This currently only supports block indentation for closing parentheses.

Make sure we do not try to change line comments that are non-regular, i.e. do
not start with "//" or "#". This can for example happen when "//" is
broken into two lines with an escaped newline.
1. IndexTokenSource::getNextToken cannot return nullptr; some code was
still written assuming it can; make getNextToken more resilient against
incorrect input and fix its call-sites.
2. Change various asserts that can happen due to user provided input to
conditionals in the code.
Add a new option PackConstructorInitializers and deprecate the
related options ConstructorInitializerAllOnOneLineOrOnePerLine and
AllowAllConstructorInitializersOnNextLine. Below is the mapping:

CurrentLine true false
NextLine true true

I find as I develop I'm moving between many different languages C++,C#,JavaScript all the time. As I move between the file types I like to keep `clang-format` as my formatting tool of choice. (hence why I initially added C# support in {D58404}) I know those other languages have their own tools but I have to learn them all, and I have to work out how to configure them, and they may or may not have integration into my IDE or my source code integration.
I am increasingly finding that I'm editing additional JSON files as part of my daily work and my editor and git commit hooks are just not setup to go and run [[ https://stedolan.github.io/jq/ | jq ]], So I tend to go to [[ https://jsonformatter.curiousconcept.com/ | JSON Formatter ]] and copy and paste back and forth. To get nicely formatted JSON. This is a painful process and I'd like a new one that causes me much less friction.
This has come up from time to time:

I would like to stop having to do that and have formatting JSON as a first class clang-format support `Language` (even if it has minimal style settings at present).
This revision adds support for formatting JSON using the inbuilt JSON serialization library of LLVM, With limited control at present only over the indentation level
This adds an additional Language into the .clang-format file to separate the settings from your other supported languages.
