Ted Kremenek 9deaef7f44 NSErrorChecker: remove quoting the parameter name in the diagnostic until we actually include it's name. 
This is a possible regression of moving to using ImplicitNullDerefEvent.
Fixing this for real (including the parameter name) requires more
plumbing in ImplicitNullDerefEvent.  This is just a stop gap fix.

Daniel Jasper c0880a904b Let the formatter ignore UnwrappedLines containing errors. 
This prevents code like:

namespace {
class Foo {
  Foo(
  };
}  // comment

from causing segfaults (see llvm.org/PR14774).

The line information was changed when emitting debug information for all the
DeclRefExprs and we should change it back to get ready for PopClenupBlocks

Rafael Espindola d2ecc139f2 Warn on unused auto variables. 
To do so we have to wait until we know that the type of a variable has been
deduced. Sema::FinalizeDeclaration is the first callback that is used for
decl with or without initializers.

Argyrios Kyrtzidis f86e8cced6 DiagnosticIds: Fix offset/ID calculation, no impact outside this code. 
Patch by Will Dietz:

Minor touchup so the values of Offset/ID reflect their intention.
Previously, the sum (Offset+ID) was correct, but Offset/ID
individually were wrong.

Caught by investigating unsigned overflow reported by -fsanitize=integer.

Manuel Klimek b69e3c6201 Fixes multiple formatting bugs. 
Fixes:
- incorrect handling of multiple consecutive preprocessor directives
- crash when trying to right align the escpaed newline for a line that
  is longer than the column limit
- using only ColumnLimit-1 columns when layouting with escaped newlines
  inside preprocessor directives

Daniel Jasper 90e51fdbab Don't allow line breaks after template parameters. 
This fixes llvm.org/PR14786.

We will need to split there as a last resort, but that should be done
consistently independent of whether the type is a template type or not.

Before:
template <typename T>
aaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaa<T>
                    ::aaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

After:
template <typename T>
aaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaa,
                    aaaaaaaaaaaaaaaaaaaaaaaaaa<T>::aaaaaaaaaa,
                    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

Daniel Jasper 3c0431c887 Format */& as binary operator if followed by a unary operator. 
This fixes llvm.org/PR14687.
Also fixes segfault for lines starting with * or &.

Before:
a *~b;
*a = 1;  // <- this segfaulted

After:
a * ~b;
*a = 1;  // no segfault :-)

Manuel Klimek a71e5d8115 Fixes use of unescaped newlines when formatting preprocessor directives. 
This is the first step towards handling preprocessor directives. This
patch only fixes the most pressing issue, namely correctly escaping
newlines for tokens within a sequence of a preprocessor directive.

The next step will be to fix incorrect format decisions on #define
directives.

Daniel Jasper ac5c1c286c Prefer splitting after "template <...>" and fix indentation. 
This addresses llvm.org/PR14699

Before:
template <typename T>
    void looooooooooooooooooooooongFunction(int Param1, int Param2);
template <typename T> void looooooooooooooooooooongFunction(
    int Paaaaaaaaaaaaaaaaaaaaram1, int Paaaaaaaaaaaaaaaaaaaaram2);

After:

template <typename T>
