9fb676a254 clang-format: Make exception to AlwaysBreakBeforeMultilineStrings more
conservative.

In particular, this fixes an unwanted corner case.

Before:
  string s =
      someFunction("aaaa"
                   "bbbb");

After:
  string s = someFunction(
      "aaaa"
      "bbbb");

1bf729cee1 clang-format: Row back on the AlwaysBreakBeforeMultilineStrings change.
It was a bit too aggressive.

With this patch, we keep on breaking here:
  aaaaaaaaaaaaa(aaaaaaa,
                "aaaaaaa"
                "bbbbbbb");

But don't break in:
  aaaaaaaaaaaaa(aaaaaaa, aaaaaaaa("aaaaaaa"
                                  "bbbbbbb"));

ed3f395773 clang-format: [JS] Add a special case for indenting function literals.
Before:
  var func =
      function() {
        doSomething();
      };

After:
  var func =
      function() {
    doSomething();
  };

This is a very narrow special case which fixes most of the discrepency
with what our users do. In the long run, we should try to come up with
a more generic fix for indenting these.

2aaedd3a7e clang-format: Make AlwaysBreakBeforeMultilineStrings more conservative.
In essence this is meant to consistently indent multiline strings by a
fixed amount of spaces from the start of the line. Don't do this in
cases where it wouldn't help anyway.

Before:
  someFunction(aaaaa,
               "aaaaa"
               "bbbbb");

After:
  someFunction(aaaaa, "aaaaa"
                      "bbbbb");

  auto aaaaaaaaaaaaaaaaaaaaaa(T t) -> decltype(eaaaaaaaaaaaaaaa<T>(t.a)
                                                   .aaaaaaaa());

      -> decltype(eaaaaaaaaaaaaaaa<T>(t.a).aaaaaaaa());

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

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.

c4144ea418 clang-format: Improve nested block / lambda indentation when wrapping

Basically, it doesn't seem right to indent a nested block aligned to a
binary or ternary operator.

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.

98f8ae34da clang-format: Slightly change indentation rules in for loops.
There was already a TODO to double-check whether the extra indenation
makes sense. A slightly different case reveals that it is actively harmful:

  for (int i = 0; i < aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ||
                      bbbbbbbbbbbbbbbbbbbb < ccccccccccccccc;
       ++i) {
  }

Here (and it is probably not a totally infrequent case, it just works out that
"i < " is four spaces and so the four space extra indentation makes the
operator precedence confusing. So, this will now instead be formatted
as:

  for (int i = 0; i < aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ||
                  bbbbbbbbbbbbbbbbbbbb < ccccccccccccccc;
       ++i) {
  }

After:
  bool value = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
                       + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
                       + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
                   == aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
                              * bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
                          + bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
               && aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
                          * aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
                      > ccccccccccccccccccccccccccccccccccccccccc;
