Daniel Jasper 6f2b88a398 clang-format: More eagerly wrap trailing return types.
Before:
  template <typename T>
  auto aaaaaaaaaaaaaaaaaaaaaa(T t) -> decltype(eaaaaaaaaaaaaaaa<T>(t.a)
                                                   .aaaaaaaa());

After:
  template <typename T>
  auto aaaaaaaaaaaaaaaaaaaaaa(T t)
      -> decltype(eaaaaaaaaaaaaaaa<T>(t.a).aaaaaaaa());

Also add a test case for a difficult template parsing case I stumbled accross.
Needs fixing.

Daniel Jasper 3b0f304517 clang-format: [JS] Let fat arrows have 'Assignment' precedence.
This is a more correct representation than using "Equality" introduced
in r238942 which was a quick fix to solve an actual regression.

According to the typescript spec, arrows behave like "low-precedence"
assignments.

Before:
  var a = a.aaaaaaa((a: a) => aaaaaaaaaaaaaaaaaaaaa(bbbbbbbbb) &&
                    aaaaaaaaaaaaaaaaaaaaa(bbbbbbb));
After:
  var a = a.aaaaaaa((a: a) => aaaaaaaaaaaaaaaaaaaaa(bbbbbbbbb) &&
                              aaaaaaaaaaaaaaaaaaaaa(bbbbbbb));

Daniel Jasper 3c306e895e clang-format: [JS] Let fat arrows have 'Equality' precedence.
This fixes a regression in literal formatting:

Before:
  aaaaaaaaaaaaa = {
    aaaaaaaaaaaaaaaaaaaaaaaaaaaa: (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                                   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) =>
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
  };

After:
  var aaaaaaaaaaaaaaaaaaaa = {
    aaaaaaaaaaaaaaaaaaaaaaaaaaaa:
        (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
         aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) =>
                aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
  };

Also apply no-else-after-return policy.

Daniel Jasper 1699eca119 clang-format: [JS] Making arrow function wrapping more consistent.
Before:
  someFunction(() =>
               {
                 doSomething();  // break
               })
      .doSomethingElse(  // break

After:
  someFunction(() => {
    doSomething();  // break
  })
      .doSomethingElse(  // break
          );

This is still bad, but at least it is consistent with what we do for other
function literals. Added corresponding tests.

Manuel Klimek 3d3ea84a4f Refactor clang-format's formatter.
Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
   of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
   LineJoiner iterate over the lines so we never operate on a line that might
   be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.

Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
   only the outer expression was affected:
   int x = s({ // clang-format only this line
     class X {
       public:
    // ^ this starts at the non-modified indnent level; previously we would
    //   not fix this, now we correctly outdent it.
