This allows matchers like:
friendDecl(hasType(cxxRecordDecl(...)))
friendDecl(hasType(asString(...)))
It seems that hasType is probably the most reasonable narrowing matcher to
overload, since it is already used to narrow to other declaration kinds.

The specifiesTypeLoc() matcher narrows a nestedNameSpecifier matcher based on a

are a namespace, and cause getTypeLoc to assert-fail.

WebKit C++ style for object initialization is as follows:
Foo foo { bar };
Yet using clang-format -style=webkit changes this to:
Foo foo{ bar };
As there is no existing combination of rules that will ensure a space
before a braced list in this fashion, this patch adds a new
SpaceBeforeCpp11BracedList rule.

```
The root cause was that BreakableToken was not considering the case of a reflow between an unescaped newline in a line comment.

Summary:
Currently clang-format allows this for text protos:
```
submessage:
{ key: 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa' }
```
when it is under the column limit and when putting it all on one line exceeds the column limit.
This is not a very intuitive formatting, so I'd prefer having
```
submessage: {
key: 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'
}
```
instead, even if it takes one line more.
This patch prevents clang-format from inserting a break between `: {` and similar cases.

TypeScript uses the `!` token for strict property initialization

Summary:
This option replaces the BreakBeforeInheritanceComma option with an
enum, thus introducing a mode where the colon stays on the same line as
constructor declaration:
// When it fits on line:
class A : public B, public C {
...
};
// When it does not fit:
class A :
public B,
public C {
...
};
This matches the behavior of the `BreakConstructorInitializers` option,
introduced in https://reviews.llvm.org/D32479.

Summary:
This patch updates clang-format text protos to put entries of a submessage into separate lines if the submessage contains at least two entries and contains at least one submessage entry.
For example, the entries here are kept on separate lines even if putting them on a single line would be under the column limit:
```
message: {
entry: 1
submessage: { key: value }
}
```
Messages containing a single submessage or several scalar entries can still be put on one line if they fit:
```
message { submessage { key: value } }
message { x: 1 y: 2 z: 3 }

llvm-svn: 334070
Summary:
Please take a close look at this CL. I haven't touched much of
`UnwrappedLineParser` before, so I may have gotten things wrong.
Previously, clang-format would incorrectly format the following:
```
@implementation Foo
- (Class)class {
}
- (void)foo {
}
@end
```
as:
```
@implementation Foo
- (Class)class {
}
- (void)foo {
}
@end
```
The problem is whenever `UnwrappedLineParser::parseStructuralElement()`
sees any of the keywords `class`, `struct`, or `enum`, it calls
`parseRecord()` to parse them as a C/C++ record.
This causes subsequent lines to be parsed incorrectly, which
causes them to be indented incorrectly.
In Objective-C/Objective-C++, these keywords are valid selector
components.
This diff fixes the issue by explicitly handling `+` and `-` lines
inside `@implementation` / `@interface` / `@protocol` blocks
and parsing them as Objective-C methods.

Summary:
We fail to import a `ClassTemplateDecl` if the "To" context already
contains a definition and then a forward decl. This is because
`localUncachedLookup` does not find the definition. This is not a
lookup error, the parser behaves differently than assumed in the
importer code. A `DeclContext` contains one DenseMap (`LookupPtr`)
which maps names to lists. The list is a special list `StoredDeclsList`
which is optimized to have one element. During building the initial
AST, the parser first adds the definition to the `DeclContext`. Then
during parsing the second declaration (the forward decl) the parser
again calls `DeclContext::addDecl` but that will not add a new element
to the `StoredDeclsList` rarther it simply overwrites the old element
with the most recent one. This patch fixes the error by finding the
definition in the redecl chain. Added tests for the same issue with
`CXXRecordDecl` and with `ClassTemplateSpecializationDecl`. These tests
pass and they pass because in `VisitRecordDecl` and in
`VisitClassTemplateSpecializationDecl` we already use
`D->getDefinition()` after the lookup.

Summary:
Previously, clang-format's parser would fail to annotate the
selector in a single-component Objective-C method invocation with
`TT_SelectorName`. For example, the following:
[foo bar];
would parse `bar` as `TT_Unknown`:
M=0 C=1 T=Unknown S=0 B=0 BK=0 P=140 Name=identifier L=34 PPK=2
FakeLParens= FakeRParens=0 II=0x559d5db51770 Text='bar'
This caused us to fail to insert a space after a closing cast rparen,
so the following:
[((Foo *)foo) bar];
would format as:
[((Foo *)foo)bar];
This diff fixes the issue by ensuring we annotate the selector
in a single-component Objective-C method invocation as
`TT_SelectorName`.

Summary:
This patch changes the behavior of PenaltyBreakBeforeFirstCallParameter
so that is does not apply after a brace, when Cpp11BracedListStyle is
false.
This way, variable initialization is wrapped more like an initializer
than like a function call, which is more consistent with user
expectations for this braced list style.
With PenaltyBreakBeforeFirstCallParameter=200, this gives the following
code: (with Cpp11BracedListStyle=false)
Before :
const std::unordered_map<std::string, int> Something::MyHashTable =
{ { "aaaaaaaaaaaaaaaaaaaaa", 0 },
{ "bbbbbbbbbbbbbbbbbbbbb", 1 },
{ "ccccccccccccccccccccc", 2 } };
After :
const std::unordered_set<std::string> Something::MyUnorderedSet = {
{ "aaaaaaaaaaaaaaaaaaaaa", 0 },
{ "bbbbbbbbbbbbbbbbbbbbb", 1 },
{ "ccccccccccccccccccccc", 2 }
