Ben Hamilton 3a47fddfd3 [clang-format] Set ObjCBinPackProtocolList to Never for google style
Summary:
This is split off from D42650, and sets ObjCBinPackProtocolList
to Never for the google style.

Depends On D42650

Test Plan: New tests added. make -j12 FormatTests && ./tools/clang/unittests/Format/FormatTests

Jacek Olesiak fb7f5c08b9 [clang-format] Fix ObjC message arguments formatting.
Summary:
Fixes formatting of ObjC message arguments when inline block is a first
argument.

Having inline block as a first argument when method has multiple parameters is
discouraged by Apple:
"It’s best practice to use only one block argument to a method. If the
method also needs other non-block arguments, the block should come last"
(https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/ProgrammingWithObjectiveC/WorkingwithBlocks/WorkingwithBlocks.html#//apple_ref/doc/uid/TP40011210-CH8-SW7),
it should be correctly formatted nevertheless.

Current formatting:
```
[object blockArgument:^{
  a = 42;
}
    anotherArg:42];
```

Fixed (colon alignment):
```
[object
  blockArgument:^{
    a = 42;
  }
     anotherArg:42];
```

Ben Hamilton 56d1c01999 [clang-format] Add more tests for Objective-C 2.0 generic alignment
Summary:
In r236412, @djasper added a comment:

    // FIXME: We likely want to do this for more combinations of brackets.
    // Verify that it is wanted for ObjC, too.

In D42650, @stephanemoore asked me to confirm this.

This followup to D42650 adds more tests to verify the relative
alignment behavior for Objective-C 2.0 generics passed to functions
and removes the second half of the FIXME comment.

Test Plan:
  make -j12 FormatTests && \
  ./tools/clang/unittests/Format/FormatTests --gtest_filter=FormatTestObjC.\*

Ben Hamilton 4dc658ca52 [clang-format] New format param ObjCBinPackProtocolList
Summary:
This is an alternative approach to D42014 after some
investigation by stephanemoore@ and myself.

Previously, the format parameter `BinPackParameters` controlled both
C function parameter list bin-packing and Objective-C protocol conformance
list bin-packing.

We found in the Google style, some teams were changing
`BinPackParameters` from its default (`true`) to `false` so they could
lay out Objective-C protocol conformance list items one-per-line
instead of bin-packing them into as few lines as possible.

To allow teams to use one-per-line Objective-C protocol lists without
changing bin-packing for other areas like C function parameter lists,
this diff introduces a new LibFormat parameter
`ObjCBinPackProtocolList` to control the behavior just for ObjC
protocol conformance lists.

The new parameter is an enum which defaults to `Auto` to keep the
previous behavior (delegating to `BinPackParameters`).

Depends On D42649

Ben Hamilton 5dd4018bfc [clang-format] Add more tests for ObjC protocol list formatting behavior
Summary:
The existing unit tests in FormatTestObjC.cpp didn't fully cover
all the cases for protocol confirmance list formatting.

This extends the unit tests to more cases of protocol
conformance list formatting, especially how the behavior changes
when `BinPackParameters` changes from `true` (the default) to `false`.

  ./tools/clang/unittests/Format/FormatTests --gtest_filter=FormatTestObjC.\*

Ben Hamilton f84f118eb8 [ClangFormat] ObjCSpaceBeforeProtocolList should be true in the google style
Summary:
The Google style guide is neutral on whether there should be a
space before the protocol list in an Objective-C @interface or
@implementation.

The majority of Objective-C code in both Apple's public
header files and Google's open-source uses a space before
the protocol list, so this changes the google style to
default ObjCSpaceBeforeProtocolList to true.

Ben Hamilton e2e3e67cf1 [Format] Improve ObjC header guessing heuristic
Summary:
This improves upon the previous Objective-C header guessing heuristic
from rC320479.

Now, we run the lexer on C++ header files and look for Objective-C
keywords and syntax. We also look for Foundation types.

Ben Hamilton 687e5fa936 [ClangFormat] IndentWrappedFunctionNames should be true in the google ObjC style
Summary:
If we write the following code, it goes over 100 columns, so we need to wrap it:

```
- (VeryLongReturnTypeName)veryLongMethodParameter:(VeryLongParameterName)thisIsAVeryLongParameterName
                              longMethodParameter:(LongParameterName)thisIsAlsoAnotherLongParameterName;
```

Currently, clang-format with the google style aligns the method parameter names on the first column:

```
- (VeryLongReturnTypeName)
veryLongMethodParameter:(VeryLongParameterName)thisIsAVeryLongParameterName
    longMethodParameter:(LongParameterName)thisIsAlsoAnotherLongParameterName;
```

We'd like clang-format in the google style to align these to column 4 for Objective-C:

```
- (VeryLongReturnTypeName)
    veryLongMethodParameter:(VeryLongParameterName)thisIsAVeryLongParameterName
            longMethodParameter:(LongParameterName)thisIsAlsoAnotherLongParameterName;
```

Krasimir Georgiev 11ef531b5c [clang-format] Improve ObjC headers detection.
This patch improves detection of ObjC header files.
Right now many ObjC headers, especially short ones, are categorized as C/C++.

Way of filtering still isn't the best, as most likely it should be token-based.

Daniel Jasper 03a04fe95f clang-format: Separate out a language kind for ObjC.
While C(++) and ObjC are generally formatted the same way and can be
mixed, people might want to choose different styles based on the
language. This patch recognizes .m and .mm files as ObjC and also
implements a very crude detection of whether or not a .h file contains
ObjC code. This can be improved over time.

Also move most of the ObjC tests into their own test file to keep file
size maintainable.
