Summary:
Introduce `PenaltyBreakTemplateDeclaration` to control the penalty,
and change `AlwaysBreakTemplateDeclarations` to an enum with 3 modes:
* `No` for regular, penalty based, wrapping of template declaration
* `MultiLine` for always wrapping before multi-line declarations (e.g.
same as legacy behavior when `AlwaysBreakTemplateDeclarations=false`)
* `Yes` for always wrapping (e.g. same as legacy behavior when
`AlwaysBreakTemplateDeclarations=true`)

- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM

The new behaviors in this patch:

- When inserting multiple #includes to the end of a file which doesn't
end with a "\n" character, a "\n" will be prepended to each #include.
This is a special and rare case that was previously handled. This is now

This required a couple of yaks to be shaved:
1. MatchingOpeningBlockLineIndex was misused to also store the
closing index; instead, use a second variable, as this doesn't
work correctly for "} else {".
2. We needed to change the API of AffectedRangeManager to not
use iterators; we always passed in begin / end for the whole
container before, so there was no mismatch in generality.
3. We need an extra check to discontinue formatting at the top
level, as we now sometimes change the indent of the closing
brace, but want to bail out immediately afterwards, for
example:
void f() {
if (a) {
}
void g();
Previously:
void f() {

Summary:
When I wrote `ObjCHeaderStyleGuesser`, I incorrectly assumed the
correct way to iterate over all tokens in `AnnotatedLine` was to
iterate over the linked list tokens starting with
`AnnotatedLine::First`.
However, `AnnotatedLine` also contains a vector
`AnnotedLine::Children` with child `AnnotedLine`s which have their own
tokens which we need to iterate over.
Because I didn't iterate over the tokens in the children lines, the
ObjC style guesser would fail on syntax like:
#define FOO ({ NSString *s = ... })
as the statement(s) inside { ... } are child lines.
This fixes the bug and adds a test. I confirmed the test
failed before the fix, and passed after the fix.

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`).

Adding the new enumerator forced a bunch more changes into this patch than I
would have liked. The -Wtautological-compare warning was extended to properly
check the new comparison operator, clang-format needed updating because it uses
precedence levels as weights for determining where to break lines (and several
operators increased their precedence levels with this change), thread-safety
analysis needed changes to build its own IL properly for the new operator.
All "real" semantic checking for this operator has been deferred to a future
patch. For now, we use the relational comparison rules and arbitrarily give
the builtin form of the operator a return type of 'void'.

Summary:
This is an implementation for [bug 17362](https://bugs.llvm.org/attachment.cgi?bugid=17362) which adds support for indenting preprocessor statements inside if/ifdef/endif. This takes previous work from fmauch (https://github.com/fmauch/clang/tree/preprocessor_indent) and makes it into a full feature.
The context of this patch is that I'm a VMware intern, and I implemented this because VMware needs the feature. As such, some decisions were made based on what VMware wants, and I would appreciate suggestions on expanding this if necessary to use-cases other people may want.
This adds a new enum config option, `IndentPPDirectives`. Values are:
* `PPDIS_None` (in config: `None`):
```
#if FOO
#if BAR
#include <foo>
#endif
#endif
```
* `PPDIS_AfterHash` (in config: `AfterHash`):
```
#if FOO
# if BAR
# include <foo>
# endif
#endif
```
This is meant to work whether spaces or tabs are used for indentation. Preprocessor indentation is independent of indentation for non-preprocessor lines.
Preprocessor indentation also attempts to ignore include guards with the checks:
1. Include guards cover the entire file
2. Include guards don't have `#else`
3. Include guards begin with
```
#ifndef <var>
#define <var>
```
This patch allows `UnwrappedLineParser::PPBranchLevel` to be decremented to -1 (the initial value is -1) so the variable can be used for indent tracking.
Defects:
* This patch does not handle the case where there's code between the `#ifndef` and `#define` but all other conditions hold. This is because when the #define line is parsed, `UnwrappedLineParser::Lines` doesn't hold the previous code line yet, so we can't detect it. This is out of the scope of this patch.
* This patch does not handle cases where legitimate lines may be outside an include guard. Examples are `#pragma once` and `#pragma GCC diagnostic`, or anything else that does not change the meaning of the file if it's included multiple times.
* This does not detect when there is a single non-preprocessor line in front of an include-guard-like structure where other conditions hold because `ScopedLineState` hides the line.
* Preprocessor indentation throws off `TokenAnnotator::setCommentLineLevels` so the indentation of comments immediately before indented preprocessor lines is toggled on each run. Fixing this issue appears to be a major change and too much complexity for this patch.

This is a short-term fix for PR33650 aimed to get the modules build bots green again.
Remove all the places where we use the LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR
macros to try to locally specialize a global template for a global type. That's
not how C++ works.
Instead, we now centrally define how to format vectors of fundamental types and
of string (std::string and StringRef). We use flow formatting for the former
cases, since that's the obvious right thing to do; in the latter case, it's
less clear what the right choice is, but flow formatting is really bad for some
cases (due to very long strings), so we pick block formatting. (Many of the
cases that were using flow formatting for strings are improved by this change.)
Other than the flow -> block formatting change for some vectors of strings,
this should result in no functionality change.

* SplitEmptyUnion
* SplitEmptyNamespace
The `SplitEmptyFunction` option name has also been simplified/
shortened (from `SplitEmptyFunctionBody`).
These options are helpful when the correspond AfterXXX option is
enabled, to allow merging the empty record:
class Foo
{};
In addition, this fixes an unexpected merging of short records, when
the AfterXXXX options are used, which caused to be formatted like
this:
class Foo
{ void Foo(); };
This is now properly formatted as:
class Foo
{
void Foo();

improve support for LLVM-style include sorting.
This really is a collection of improvements to the rules for LLVM
include sorting:
- We have gmock headers now, so it adds support for those to one of the
categories.
- LLVM does use 'FooTest.cpp' files to test 'Foo.h' so it adds that
suffix for finding a main header.
- At times the test file's case may not match the header file's case, so
switch to case-insensitive regex matching of header names.
With this set of changes, I can't spot any misbehaviors when re-sorting

Summary:
@see is special among JSDoc tags in that it is commonly followed by URLs. The JSDoc spec suggests that users should wrap URLs in an additional {@link url...} tag (@see http://usejsdoc.org/tags-see.html), but this is very commonly violated, with @see being followed by a "naked" URL.
This change special cases all JSDoc lines that contain an @see not to be wrapped to account for that.

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,

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

The attempt to fix requoting behavior in r280487 after changes to
tooling::Replacements are incomplete. We essentially need to add to
replacements at the same position, one to insert a line break and one to
change the quoting and that's incompatible with the new
tooling::Replacement API, which does not allow for order-dependent
Replacements. To make the order clear, Replacements::merge() has to be
used, but that requires the merged Replacement to actually refer to the
changed text, which is hard to reproduce for the requoting.
This change fixes the behavior by moving the requoting to a completely
separate pass. The added benefit is that no weird ColumnWidth
calculations are necessary anymore and this should just work even if we
implement string literal splitting in the future.
llvm-svn: 280874

Turns "foo" into 'foo' (or vice versa, depending on configuration).
This makes it more convenient to follow the Google JavaScript style
