3ae6f5a47b clang-format: Improve format of calls with several lambdas.
Before:
  SomeFunction([]() {
                 int i = 42;
                 return i;
               },
               []() {
    int j = 43;
    return j;
  });

After:
  SomeFunction([]() {
                 int i = 42;
                 return i;
               },
               []() {
                 int j = 43;
                 return j;

b48d3afcd5 clang-format: Keep more trailing annotations on the same line.
More precisely keep all short annotations (<10 characters) on the same
line if possible. Previously, clang-format would only prefer to do so
for "const", "override" and "final". However, it seems to be generally
preferable, especially because some codebases have to wrap those in
macros for backwards compatibility.

Before:
  void someLongFunction(int someLongParameter)
      OVERRIDE {}

After:
  void someLongFunction(
      int someLongParameter) OVERRIDE {}

This fixes llvm.org/PR19363.

d74cf40386 clang-format: Extend AllowShortFunctions.. to only merge inline functions.
Before AllowShortFunctionsOnASingleLine could either be true, merging
all functions, or false, merging no functions. This patch adds a third
value "Inline", which can be used to only merge short functions defined
inline in a class, i.e.:

  void f() {
    return 42;
  }

  class C {
    void f() { return 42; }
  };

5c33265c9e clang-format: Prefer an additional line-break over hanging indent.
Don't allow the RHS of an operator to be split over multiple
lines unless there is a line-break right after the operator.

Before:
  if (aaaa && bbbbb || // break
                  cccc) {
  }

After:
  if (aaaa &&
      bbbbb || // break
          cccc) {
  }

In most cases, this seems to increase readability.

819788da83 Fix crasher bug.
Due to not resetting the fake rparen data on the token when iterating
over annotated lines, we would pop the last element of the paren stack.

This patch fixes the underlying root cause, and makes the code more
robust against similar problems in the future:
- reset the first token when iterating on the same annotated lines due
  to preprocessor branches
- never pop the last element from the paren stack, so we do not crash,
  but rather incorrectly format
- add assert()s so we can figure out if our assumptions are violated
