Alexander Kornienko 67d9c8c87e Fix alignment of trailing block comments.
Summary:
This patch ensures that the lines of the block comments retain relative
column offsets. In order to do this WhitespaceManager::Changes representing
continuation of block comments keep a pointer on the change representing the
whitespace change before the block comment, and a relative column offset to this
change, so that the correct column can be reconstructed at the end of alignment
process.

Daniel Jasper 98583d522f clang-format: Early cut-off for inlining nested blocks.
Specifically, for a nested block or lambda, don't try to put the single
statement body inline, if it exceeds the column limit.

This should not change any observable behavior (as those would never
have led to the 'best' solution), but significantly speeds up formatting
time.

Daniel Jasper 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)

  void someLongFunction(

Before AllowShortFunctionsOnASingleLine could either be true, merging

Manuel Klimek 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
