LLVM/Clang basically don't use such comments and for Google-style,
include-lines are explicitly exempt from the column limit. Also, for
most cases, where the column limit is violated, the "better" solution
would be to move the comment to before the include, which clang-format
cannot do (yet).

llvm-svn: 181191

clang-format did not indent any declarations/definitions when breaking
after the type. With this change, it indents for all declarations but
does not indent for function definitions, i.e.:

Before:
const SomeLongTypeName&
some_long_variable_name;
typedef SomeLongTypeName
SomeLongTypeAlias;
const SomeLongReturnType*
SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }

After:
const SomeLongTypeName&
    some_long_variable_name;
typedef SomeLongTypeName
    SomeLongTypeAlias;
const SomeLongReturnType*
    SomeLongFunctionName();
const SomeLongReturnType*
SomeLongFunctionName() { ... }

While it might seem inconsistent to indent function declarations, but
not definitions, there are two reasons for that:
- Function declarations are very similar to declarations of function
type variables, so there is another side to consistency to consider.
- There can be many function declarations on subsequent lines and not
indenting can make them harder to identify. Function definitions
are already separated by their body and not indenting
makes the function name slighly easier to find.

This problem can only happen in C++11.

This seems to be more common in LLVM, Google and Chromium.

Before:
class AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA :
    public BBBBBBBBBBBBBBBBBBBBBBBBBBBBBB,
    public CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC {
};

After:
class AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
    : public BBBBBBBBBBBBBBBBBBBBBBBBBBBBBB,
      public CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC {
};

I was not able to find a case (other than the fix in r181163) where this
makes a difference, but it is a more obviously correct API to have.

This fixes pr14958. I will audit other calls to isExternCContext to see
if there are any similar bugs left.

Missing (somewhat ironically) is support for the new deduction rules

to use. This makes very little difference right now (other than suppressing
follow-on errors in some cases), but will matter more once we support deduced
return types (we don't want expressions with undeduced return types in the
AST).

This change required some minor changes to LocationContextMap to have it map
from PathPieces to LocationContexts instead of PathDiagnosticCallPieces to
LocationContexts.  These changes are in the other diagnostic
generation logic as well, but are functionally equivalent.

Interestingly, this optimize requires delaying "cleanUpLocation()" until
later; possibly after all edges have been optimized.  This is because
we need PathDiagnosticLocations to refer to the semantic entity (e.g. a statement)
as long as possible.  Raw source locations tell us nothing about
the semantic relationship between two locations in a path.
