Function declarations are now broken with the following preferences:
1) break amongst arguments.
2) break after return type.
3) break after (.
4) break before after nested name specifiers.
Options #2 or #3 are preferred over #1 only if a substantial number of
lines can be saved by that.

Also remove duplicate methods calculating properties of AnnotatedTokens
and make them members of AnnotatedTokens so that they are in a common
place.

isVirtual - matches CXXMethodDecl nodes for virtual methods
isOverride - matches CXXMethodDecl nodes for methods that override virtual methods from a base class.

Summary:
Some codebases use these kinds of macros in functions, e.g. Chromium's
IPC_BEGIN_MESSAGE_MAP, IPC_BEGIN_MESSAGE_HANDLER, etc.

The idea is to indent according to operator precedence and pretty much
identical to how stuff would be indented with parenthesis.
Before:
bool value = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ==
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb +
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb &&
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa >
ccccccccccccccccccccccccccccccccccccccccc;
After:
bool value = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ==
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb +
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb &&
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa >
ccccccccccccccccccccccccccccccccccccccccc;

This combines several related changes:
a) Don't break before after the variable types in for loops with a
single variable.
b) Better indent DeclStmts defining multiple variables.
Before:
bool aaaaaaaaaaaaaaaaaaaaaaaaa =
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaa),
bbbbbbbbbbbbbbbbbbbbbbbbb =
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb(bbbbbbbbbbbbbbbb);
for (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaa = aaaaaaaaaaaaaaaa.aaaaaaaaaaaaaaa;
aaaaaaaaaaa != aaaaaaaaaaaaaaaaaaa; ++aaaaaaaaaaa) {
}
After:
bool aaaaaaaaaaaaaaaaaaaaaaaaa =
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaa),
bbbbbbbbbbbbbbbbbbbbbbbbb =
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb(bbbbbbbbbbbbbbbb);
for (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaa =
aaaaaaaaaaaaaaaa.aaaaaaaaaaaaaaa;
aaaaaaaaaaa != aaaaaaaaaaaaaaaaaaa; ++aaaaaaaaaaa) {
}

Summary:
It turns out that we don't need to store CommentsBeforeNextToken in the
line state, but rather flush them before we start parsing preprocessor
directives. This fixes wrong comment indentation in code blocks in macro calls
(the test is included).

Basically we have always special-cased the top-level statement of an
unwrapped line (the one with ParenLevel == 0) and that lead to several
inconsistencies. All added tests were formatted in a strange way, for
example:
Before:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();
if (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()) {
}
After:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();
if (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()) {
}
llvm-svn: 178542
Comments before preprocessor directives used to be stored with InPPDirective
flag set, which prevented correct comment splitting in this case. Fixed by
flushing comments before switching on InPPDirective. Added a new test and fixed
one of the existing tests.

It turns out that
-foo;
can be an objective C method declaration. So instead of the previous
solution, recognize objective C methods only if we are in a declaration
scope.

Before:
int a; // not formatted
// formatting this line only
After:

This makes clang-format stable independent of whether the whole
file or single lines are formatted in most cases.

Apparently one needs to set LangOptions.LineComment.
Before "//* */" got reformatted to "/ /* */" as the lexer was returning
the token sequence (slash, comment). This could also lead to weird other
stuff, e.g. for people that like to using comments like:
//****************
llvm-svn: 177720
Summary:
1. When splitting one-line block comment, use indentation and *s.
2. Remove trailing whitespace from all lines of a comment, not only the ones being splitted.
3. Add backslashes for all lines if a comment is used insed a preprocessor directive.

This seems to be generally more desired.
Before:
if (aaaaaaaa &&
bbbbbbbb >
cccccccc) {}
After:
if (aaaaaaaa &&

Also: Some formatting cleanup on clang-format's files.
llvm-svn: 177514
clang-format already prevented sequences like:
...
SomeParameter).someFunction(
...
as those are quite confusing. This failed on:
...
SomeParameter).someFunction(otherFunction(
...
Fixed in this patch.

This yields a log(#ast_nodes) worst-case improvement with matchers like
stmt(unless(hasAncestor(...))).
Also made the order of visitation for ancestor matches BFS, as the most
common use cases (for example finding the closest enclosing function
definition) rely on that.

The stronger binding of a string ending in :/= does not really make
sense if it is the only character.
