Anna Zaks 5f37643de1 [analyzer] Fix a false positive in the ivar invalidation checker.
When a property is "inherited" through both a parent class and directly
through a protocol, we should not require the child to invalidate it
since the backing ivar belongs to the parent class.
(Fixes radar://12913734)

Manuel Klimek 28cacc740d Fix parsing of variable declarations directly after a class / struct.
Previous indent:
class A {
}
a;
void f() {
};

With this patch:
class A {
} a;
void f() {
}
;

The patch introduces a production for classes and structs, and parses
the rest of the line to the semicolon after the class scope.
This allowed us to remove a long-standing wart in the parser that would
just much the semicolon after any block.
Due to this suboptimal formating some tests were broken.

Some unrelated formatting tests broke; those hit a bug in the ast
printing, and need to be fixed separately.

Michael Han 309af291ef Add fixit hints for misplaced C++11 attributes around class specifiers.
Following r168626, in class declaration or definition, there are a combination of syntactic locations 
where C++11 attributes could appear, and among those the only valid location permitted by standard is
between class-key and class-name. So for those attributes appear at wrong locations, fixit is used to 
move them to expected location and we recover by applying them to the class specifier.

David Tweed 042e0883cb Scalar shifts in the OpenCL specification (as of v. 1.2) are defined to be
with respect to the lower "left-hand-side bitwidth" bits, even when negative);
see OpenCL spec 6.3j. This patch both implements this behaviour in the code
generator and "constant folding" bits of Sema, and also prevents tests
to detect undefinedness in terms of the weaker C99 or C++ specifications
from being applied.

Daniel Jasper 206df73417 Prefer not to break after assignments.
This addresses llvm.org/PR14830.

Before:
unsigned Cost =
    TTI.getMemoryOpCost(I->getOpcode(), VectorTy, SI->getAlignment(),
                        SI->getPointerAddressSpace());
CharSourceRange LineRange =
    CharSourceRange::getTokenRange(TheLine.Tokens.front().Tok.getLocation(),
                                   TheLine.Tokens.back().Tok.getLocation());

After:
unsigned Cost = TTI.getMemoryOpCost(I->getOpcode(), VectorTy,
                                    SI->getAlignment(),
                                    SI->getPointerAddressSpace());
CharSourceRange LineRange = CharSourceRange::getTokenRange(
                                TheLine.Tokens.front().Tok.getLocation(),
                                TheLine.Tokens.back().Tok.getLocation());

This required rudimentary changes to static initializer lists, but we
are not yet formatting them in a reasonable way. That will be done in a
subsequent patch.

Daniel Jasper da16db3f9a Do not break before "0" in pure virtual function declarations.
Before:
virtual void write(ELFWriter *writer, OwningPtr<FileOutputBuffer> &buffer) =
    0

After:
virtual void write(ELFWriter *writerrr,
                   OwningPtr<FileOutputBuffer> &buffer) = 0;

This addresses llvm.org/PR14815.

To implement this I introduced a line type during parsing and moved the
definition of TokenType out of the struct for increased readability.
Should have done the latter in a separate patch, but it would be hard to
pull apart now.

Manuel Klimek 38ba11e492 Do not ever allow using the full line in preprocessor directives.
We would format:
  #define A \
    int f(a); int i;
as
  #define A \
    int f(a);\
    int i

The fix will break up macro definitions that could fit a line, but hit
the last column; fixing that is more involved, though, as it requires
looking at the following line.

Manuel Klimek c74d292229 Fix layouting of single-line-comments preceded by an escaped newline.
Previously, we'd format
  int i;\
  // comment
as
  int i; // comment

The problem is that the escaped newline is part of the next token, and
thus the raw token text of the comment doesn't start with "//".

Manuel Klimek ef92069940 Fix layouting of tokens with a leading escaped newline.
If a token follows directly on an escaped newline, the escaped newline
is stored with the token. Since we re-layout escaped newlines, we need
to treat them just like normal whitespace - thus, we need to increase
the whitespace-length of the token, while decreasing the token length
(otherwise the token length contains the length of the escaped newline
and we double-count it while indenting).

Manuel Klimek 1058d987f9 Fixes handling of unbalances braces.
If we find an unexpected closing brace, we must not stop parsing, as
we'd otherwise not layout anything beyond that point.

If we find a structural error on the highest level we'll not re-indent
anyway, but we'll still want to format within unwrapped lines.

Needed to introduce a differentiation between an expected and unexpected
closing brace.

Manuel Klimek 52d0fd8961 Fixes parsing of hash tokens in the middle of a line.
To parse # correctly, we need to know whether it is the first token in a
line - we can deduct this either from the whitespace or seeing that the
token is the first in the file - we already calculate this information.
This patch moves the identification of the first token into the
getNextToken method and stores it inside the FormatToken, so the
UnwrappedLineParser can stay independent of the SourceManager.

Manuel Klimek 1abf789c7a Various fixes to clang-format's macro handling.
Some of this is still pretty rough (note the load of FIXMEs), but it is
strictly an improvement and fixes various bugs that were related to
macro processing but are also imporant in non-macro use cases.

Specific fixes:
- correctly puts espaced newlines at the end of the line
- fixes counting of white space before a token when escaped newlines are
  present
- fixes parsing of "trailing" tokens when eof() is hit
- puts macro parsing orthogonal to parsing other structure
- general support for parsing of macro definitions

Due to the fix to format trailing tokens, this change also includes a
bunch of fixes to the c-index tests.
