Summary:
This patch enables comment reflowing of lines not matching the comment pragma regex
in multiline comments containing comment pragma lines. Previously, these comments
were dumped without being reindented to the result.

Until now, NamespaceEndCommentFixer was adding missing comments for every run,
which results in multiple end comments for:
```

#if A
int a = 1;
#else
int a = 2;
#endif
```

```

Summary:
This patch makes the namespace comment fixer use the number of unwrapped lines
that a namespace spans to detect it that namespace is short, thus not needing
end comments to be added.
This is needed to ensure clang-format is idempotent. Previously, a short namespace
was detected by the original source code lines. This has the effect of requiring two
runs for this example:
```
namespace { class A; }
```
after first run:
```
namespace {
class A;
}
```
after second run:
```
namespace {
class A;
} // namespace
```

Many things were wrong:
- We didn't always allow wrapping after "as", which can be necessary.
- We used to Undestand the identifier after "as" as a start of a name.
- We didn't properly parse the structure of the expression with "as"
having the precedence of relational operators

Summary:
Async arrow functions should be marked with a whitespace after the async keyword, before the parameter list:
x = async () => foo();
Before:
x = async() => foo();
This makes it easier to tell apart an async arrow function from a call to a function called async.

r289428 added a separate language kind for Objective-C, but kept many
"Language == LK_Cpp" checks untouched. This introduced a "IsCpp()"
method that returns true for both C++ and Objective-C++, and replaces
all comparisons of Language with LK_Cpp with calls to this new method.
Also add a lot more test coverge for formatting things in LK_ObjC mode,
by having FormatTest's verifyFormat() test for LK_ObjC everything that's
being tested for LK_Cpp at the moment.
Fixes PR32060 and many other things.

This can lead to bad behavior with macros that are used to annotate
functions (e.g. ALWAYS_INLINE).
Before, this:
ALWAYS_INLINE ::std::string getName() ...
was turned into:
ALWAYS_INLINE::std::string getName() ...
If it turns out that clang-format is failing to clean up a lot of the
existing spaces now, we can add more analyses of the identifier. It
should not currently. Cases where clang-format breaks nested name
specifiers should be fine as clang-format wraps after the "::". Thus, a
line getting longer and then shorter again should lead to the same
original code.

Summary:
In JavaScript, object literals can contain methods:
var x = {
a() { return 1; },
};
Previously, clang-format always parsed nested {} inside a braced list as
further braced lists. Special case this logic for JavaScript to try
parsing as a braced list, but fall back to parsing as a child block.

Summary:
Regex detection would incorrectly classify a trailing `!` operator
(nullability cast) followed by a `/` as the start of a regular
expression literal. This fixes code such as:
var foo = x()! / 10;
Which would previously parse a regexp all the way to the end of the
source file (or next `/`).

they were previously aligned, but at different indent.
Summary:
Comment reflower was adding untouchable tokens in case two consecutive comment lines are aligned in the source code. This disallows the whitespace manager to re-indent them later.
source:
```
int i = f(abc, // line 1
d, // line 2
// line 3
b);
```
Since line 2 and line 3 are aligned, the reflower was marking line 3 as untouchable; however the three comment lines need to be re-aligned.

```
int i = f(abc, // line 1
d, // line 2
// line 3
b);
```

This rows back on r288120, r291801 and r292110. I apologize in advance
for the churn. All of those revisions where meant to make the wrapping
of RHS expressions more consistent. However, now that they are
consistent, we seem to be a bit too eager.
The reasoning here is that I think it is generally correct that we want
to line-wrap before multiline RHS expressions (or multiline arguments to
a function call). However, if there are only two of such operands or
arguments, there is always a clear vertical separation between them and
the additional line break seems much less desirable.
Somewhat good examples are expressions like:
EXPECT_EQ(2, someLongExpression(
orCall));

This only affects expressions inside ${} scopes of template strings.
Here, we want to indent relative to the surrounding template string and
not the surrounding expression. Otherwise, this can create quite a mess.

Summary:
This fixes a regression that causes example:
```
enum A {
a, // line a
// line b
b
};
```
to be formatted as follows:
```
enum A {
a, // line a
// line b
b
};
```
