Note that this might now violate the column limit and we probably need an
alternative way of indenting these then. However, that is still strictly better
than the messy formatting that clang-format did before.

clang-format: Fix another assertion discovered by the fuzzer.

In the process, fix an old todo that I don't really know how to write
tests for. The problem is that Clang's lexer creates very strange token
sequences for these. However, the new approach seems generally better
and easier to read so I am submitting it nonetheless.

The reason was that the empty line inside the comment (with just the "*") was
confusing the comment breaking logic.

clang-format: Add ability to align assignment operators.

In Objective-C some style guides use a style where assignment operators are
aligned, in an effort to increase code readability. This patch adds an option
to the format library which allows this functionality. It is disabled by
default for all the included styles, so it must be explicitly enabled.

The option will change code such as:
- (void)method {
NSNumber *one = @1;
NSNumber *twentyFive = @25;
}

to:
- (void)method {
NSNumber *one = @1;
NSNumber *twentyFive = @25;
}

Patch by Matt Oakes. Thank you!
