Summary:
Selectively propagate the information about token kind in
WhitespaceManager::replaceWhitespaceInToken.For correct alignment of new
segments of line comments in order to align them correctly. Don't set
BreakBeforeParameter in breakProtrudingToken for line comments, as it introduces
a break after the _next_ parameter. Added tests for related functions.

Summary:
"//Test" becomes "// Test". This change is aimed to improve code
readability and conformance to certain coding styles. If a comment starts with a
non-alphanumeric character, the space isn't added, e.g. "//-*-c++-*-" stays
unchanged.

Gets rid of AnnotatedToken, putting everything into FormatToken.
FormatTokens are created once, and only referenced by pointer. This
enables multiple future features, like having tokens shared between
multiple UnwrappedLines (while there's still work to do to fully enable
that).
llvm-svn: 182859
Unify handling of whitespace when breaking protruding tokens with other
whitespace replacements.
As a side effect, the BreakableToken structure changed significantly:
- have a common base class for single-line breakable tokens, as they are
much more similar
- revamp handling of multi-line comments; we now calculate the
information about lines in multi-line comments similar to normal
tokens, and always issue replacements
As a result, we were able to get rid of special casing of trailing
whitespace deletion for comments in the whitespace manager and the
BreakableToken and fixed bugs related to tab handling and escaped
newlines.
llvm-svn: 182738
Previously we started sequences to align for single line comments when
the previous line had a trailing comment, but the sequence was broken
for other reasons.
Now we re-format:
// a
// b
f(); // c
to:
// a
// b
f(); // c
llvm-svn: 182608
Now correctly leaves:
f(); // comment
// comment
g(); // comment
... alone if the middle comment was aligned with g() before formatting.
llvm-svn: 182605
Previously we would align:
f(); // comment
// other comment
g();
Even if // other comment was at the start of the line. Now we do not
align trailing comments if they have been already aligned correctly
with the next line.
Thus,
f(); // comment
// other comment
g();
will not be changed, while:
f(); // comment
// other commment
g();
will lead to the two trailing comments being aligned.
llvm-svn: 182577
Replaces the use of WhitespaceStart + WhitspaceLength.
This made a bug in the formatter obvous where we would incorrectly
calculate the next column.
FIXME: There's a similar bug left regarding TokenLength. We should
probably also move to have a TokenRange instead.
llvm-svn: 182572
Instead of selectively storing some changes and directly generating
replacements for others, we now notify the WhitespaceManager of the
whitespace before every token (and optionally with more changes inside
tokens).
Then, we run over all whitespace in the very end in original source
order, where we have all information available to correctly align
comments and escaped newlines.
The future direction is to pull more of the comment alignment
implementation that is now in the BreakableToken into the
WhitespaceManager.
This fixes a bug when aligning comments or escaped newlines in unwrapped
lines that are handled out of order:
#define A \
f({ \
g(); \
});
... now gets correctly layouted.
llvm-svn: 182467
This enables formattings like:
#define A \
int aaaa; \
int b; \
int ccc; \
int dddddddddd;
Enabling this for Google/Chromium styles only as I don't know whether it
is desired for Clang/LLVM.

Summary:
Added BreakableLineComment, moved common code from
BreakableBlockComment to newly added BreakableComment. As a side-effect of the
rewrite, found another problem with escaped newlines and had to change
code which removes trailing whitespace from line comments not to break after
this patch.

Summary:
Both strings and block comments are broken into lines in
breakProtrudingToken. Logic specific for strings or block comments is abstracted
in implementations of the BreakToken interface. Among other goodness, this
change fixes placement of backslashes after a block comment inside a
preprocessor directive (see removed FIXMEs in unit tests).
The code is far from being polished, and some parts of it will be changed for
line comments support.
