Anna Zaks 0aeb60d79d [analyzer] Add more checks to the ObjC Ivar Invalidation checker.
Restructured the checker so that it could easily find two new classes of
issues:
 - when a class contains an invalidatable ivar, but no declaration of an
invalidation method
 - when a class contains an invalidatable ivar, but no definition of an
invalidation method in the @implementation.

The second case might trigger some false positives, for example, when
the method is defined in a category.

Nico Weber a608775ba2 Formatting: In @implementation etc lines, put a space before protocol lists.
Don't do this in Google style though:
http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml#Protocols

Most other places (function declarations, variable declarations) still get
this wrong, and since this looks very similiar to template instantiations to
the lexer (`id <MyProtocol> a = ...`), it's going to be hard to fix in some
places.

Nico Weber 2bb0074232 Formatter: Add space before '(' in @implemenation, @interface, @protocol lines
The first token in @implementation, @interface, and @protocol lines is now
marked TT_ObjCDecl, and lines starting with a TT_ObjCDecl token are now marked
LT_ObjCMethodDecl.

Jordan Rose c3b23aa848 Error if an anonymous DiagGroup is referenced multiple times.
Not only is this inefficient for TableGen, it's annoying for maintenance
when renaming warning flags (unusual) or adding those flags to a group
(more likely).

This uses the new fix-it infrastructure for LLVM's SourceMgr/SMDiagnostic,
as well as a few changes to TableGen to track more source information.

Daniel Jasper c1fa281325 Improvements to function type and ObjC block formatting.
Before: int (^myBlock) (int) = ^(int num) {}
        A<void ()>;
	int (*b)(int);

After:  int (^myBlock)(int) = ^(int num) {}
        A<void()>;
	int(*b)(int);

For function types and function pointer types, this patch only makes
the behavior consistent (for types that are keywords and other types).
For the latter function pointer type declarations, we'll probably
want to add a space after "int".

Also added LangOpts.Bool = 1, so we handle "A<bool()>" appropriately
Moved the LangOpts-settings to a public place for use by tests
and clang-format binary.

Douglas Gregor 3552dabfe1 When name lookup for a redeclaration finds declarations that are known
(because they are part of some module) but have not been made visible
(because they are in a submodule that wasn't imported), filter out
those declarations unless both the old declaration and the new
declaration have external linkage. When one or both has internal
linkage, there should be no conflict unless both are imported.

Rafael Espindola 820fa707b1 Mark all subsequent decls used.
In the source

  static void f();
  static void f();
  template<typename T>
  static void g() {
    f();
  }
  static void f() {
  }
  void h() {
    g<int>();
  }

the call to f refers to the second decl, but it is only marked used at the end
of the translation unit during instantiation, after the third f decl has been
linked in.

With this patch we mark all subsequent decls used, so that it is easy to check
if a symbol is used or not.

Anna Zaks a043d0cef2 [analyzer] Include the bug uniqueing location in the issue_hash.
The issue here is that if we have 2 leaks reported at the same line for
which we cannot print the corresponding region info, they will get
treated as the same by issue_hash+description. We need to AUGMENT the
issue_hash with the allocation info to differentiate the two issues.

Add the "hash" (offset from the beginning of a function) representing
allocation site to solve the issue.

We might want to generalize solution in the future when we decide to
track more than just the 2 locations from the diagnostics.
