Switch the evaluation from isIntegerConstantExpr to EvaluateAsInt.
EvaluateAsInt will evaluate more types of expressions than
isIntegerConstantExpr.

Move one case from -Wsign-conversion to -Wconstant-conversion.  The case is:
1) Source and target types are signed
2) Source type is wider than the target type
3) The source constant value is positive
4) The conversion will store the value as negative in the target.

PropertyMap used to map IdentifierInfo (name of the property) to
ObjcPropertyDecl *. Now that a class property can have the same name as
an instance property, we change PropertyMap to map a pair <IdentifierInfo *,
unsigned> to ObjcPropertyDecl *.

Also update a few places from iterating over instance_properties to
iterating over all properties.

There are multiple, common idioms of defensive nil-checks in copy,
mutableCopy, and init methods in ObjC. The analyzer doesn't currently have the
capability to distinguish these idioms from true positives, so suppress all
warnings about returns in those families. This is a pretty blunt suppression
that we should improve later.

For

  void f() {
    union { int i; };
  }

clang used to omit the RecordDecl from the anonymous union from the AST.
That's because the code creating it only called PushOnScopeChains(), which adds
it to the current DeclContext, which here is the function's DeclContext. But
RecursiveASTVisitor doesn't descent into all decls in a FunctionDecl.

Instead, for DeclContexts that contain statements, return the RecordDecl so
that it can be included in the DeclStmt containing the VarDecl for the union.

Interesting bits from the AST before this change:

|-FunctionDecl
| `-CompoundStmt
|   |-DeclStmt
|   | `-VarDecl 0x589cd60 <col:3> col:3 implicit used 'union (anonymous at test.cc:3:3)' callinit

After this change:

-FunctionDecl
| `-CompoundStmt
|   |-DeclStmt
|   | |-CXXRecordDecl 0x4612e48 <col:3, col:18> col:3 union definition
|   | | |-FieldDecl 0x4612f70 <col:11, col:15> col:15 referenced i 'int'
|   | `-VarDecl 0x4613010 <col:3> col:3 implicit used 'union (anonymous at test.cc:3:3)' callinit

This is now closer to how anonymous struct and unions are represented as
members of structs.  It also enabled deleting some one-off code in the
template instantiation code.

Finally, it fixes a crash with ASTMatchers, see the included test case
(this fixes http://crbug.com/580749).

Add "enum ObjCPropertyQueryKind" to a few APIs that used to only take the name
of the property: ObjCPropertyDecl::findPropertyDecl,
ObjCContainerDecl::FindPropertyDeclaration,
ObjCInterfaceDecl::FindPropertyVisibleInPrimaryClass,
ObjCImplDecl::FindPropertyImplDecl, and Sema::ActOnPropertyImplDecl.

ObjCPropertyQueryKind currently has 3 values:
OBJC_PR_query_unknown, OBJC_PR_query_instance, OBJC_PR_query_class

This extra parameter specifies that we are looking for an instance property with
the given name, or a class property with the given name, or any property with
the given name (if both exist, the instance property will be returned).
