Before, clang-format would always insert a linebreak before the comment
in code like:
template <typename T> // T can be A, B or C.
struct S {};

Specifically make ConstructorInitializerAllOnOneLineOrOnePerLine work
nicely with BreakConstructorInitializersBeforeComma.
This fixes llvm.org/PR17395.

Previously, comments, could totally confuse it.
Before:
return
// true if code is one of a or b.
code == a ||
code == b;
After:
return
// true if code is one of a or b.
code == a || code == b;

Summary:
Changed UseTab to be a enum with three options: Never, Always,
ForIndentation (true/false are still supported when reading .clang-format).
IndentLevel should currently be propagated correctly for all tokens, except for
block comments. Please take a look at the general idea before I start dealing
with block comments.

Summary:
The width of the first inserted tab character depends on the initial
column, so we need to handle the first tab in a special manner.

Normally RAV visits parameter variable declarations of a function by traversing the TypeLoc of
the parameter declarations. However, for implicit functions, their parameters don't have any
TypeLoc, because they are implicit.
So for implicit functions, we visit their parameter variable declarations by traversing them through
the function declaration, and visit them accordingly.

Summary:
reformat() tries to determine the newline style used in the input
(either LF or CR LF), and uses it for the output. Maybe not every single case is
supported, but at least the bug described in http://llvm.org/PR17182 should be
resolved.

Let clang-format consistently keep up to one empty line (configured via
FormatStyle::MaxEmptyLinesToKeep) in nested blocks, e.g. lambdas. Also,
actually format single statements in nested blocks.
Before:
DEBUG({ int i; });
DEBUG({
int i;
// an empty line here would just be removed.
int j;
});
After:
DEBUG({ int i; });
DEBUG({
int i;
int j;
});

Before:
FirstToken->WhitespaceRange.getBegin()
.getLocWithOffset(First->LastNewlineOffset);
After:
FirstToken->WhitespaceRange.getBegin().getLocWithOffset(
First->LastNewlineOffset);
Re-add logic to prevent breaking after an empty set of parentheses.
Basically it seems that calling a function without parameters is more
like navigating along the same object than it is a separate step of a
builder-type call.
We might need to extends this in future to allow "short" parameters that
e.g. are an index accessing a specific element.

This fixes two issues:
1) The indent of a line comment was not adapted to the subsequent
statement as it would be outside of a nested block.
2) A missing DryRun flag caused actualy breaks to be inserted in
overly long comments while trying to come up with the best line
breaking decisions.
llvm-svn: 190123
Summary: Closure classes for C++ lambdas are always compiler-generated. This one-line change calls setImplicit(true) on them at creation time, such that a default RecursiveASTVisitor (or any for which shouldVisitImplicitCode returns false) will skip them.

Summary:
Count column width instead of the number of code points. This also
includes correct handling of tabs inside string literals and comments (with an
exception of multiline string literals/comments, where tabs are present before
the first escaped newline).
