Krasimir Georgiev 35599fdfa0 [clang-format] Break non-trailing comments, try 2
Summary:
This patch enables `BreakableToken` to manage the formatting of non-trailing
block comments. It is a refinement of https://reviews.llvm.org/D37007.
We discovered that the optimizer outsmarts us on cases where breaking the comment
costs considerably less than breaking after the comment. This patch addresses
this by ensuring that a newline is inserted between a block comment and the next
token.

Krasimir Georgiev 7f7c3dc0aa [clang-format] Emit absolute splits before lines for comments
Summary:
This patch makes the splits emitted for the beginning of comment lines during
reformatting absolute. Previously, they were relative to the start of the
non-whitespace content of the line, which messes up further TailOffset
calculations in breakProtrudingToken. This fixes an assertion failure reported
in bug 34236: https://bugs.llvm.org/show_bug.cgi?id=34236.

Summary:

In this case, the breaking column must be based on the source column of the last token that is preceded by a newline, not on the first token of the unwrapped line.

Krasimir Georgiev 13dbaa09e5 [clang-format] Fix regression about not aligning trailing comments in case they were previously aligned, but at different indent.
Summary:
Comment reflower was adding untouchable tokens in case two consecutive comment lines are aligned in the source code. This disallows the whitespace manager to re-indent them later.

source:
```
int i = f(abc, // line 1
          d, // line 2
	     // line 3
	  b);
```
Since line 2 and line 3 are aligned, the reflower was marking line 3 as untouchable; however the three comment lines need to be re-aligned.
output before:
```
int i = f(abc, // line 1
          d,   // line 2
	     // line 3
	  b);
```
output after:
```
int i = f(abc, // line 1

Daniel Jasper 7d42f3f746 [clang-format] Refactor WhitespaceManager and friends
The main motivation behind this is to cleanup the WhitespaceManager and
make it more extensible for future alignment etc. features.
Specifically, WhitespaceManager has started to copy more and more code
that is already present in FormatToken. Instead, I think it makes more
sense to actually store a reference to each FormatToken for each change.

This has as a consequence led to a change in the calculation of indent
levels. Now, we actually compute them for each Token ahead of time,
which should be more efficient as it removes an unsigned value for the
ParenState, which is used during the combinatorial exploration of the
solution space.

No functional changes intended.
