Summary:
This patch enhances Sema to check for the following restriction:
OpenMP 4.5 [2.17 Nesting of Regions]
If a target, target update, target data, target enter data, or
target exit data construct is encountered during execution of a
target region, the behavior is unspecified.

Avoids unexpected overflows while performing pointer arithmetics in 64-bit code.
Moreover, neither PointerDiffType nor 'int' can be used as a common array index
type because arrays may have size (and indexes) more than PTRDIFF_MAX but less
than SIZE_MAX.

Consider the following ObjC++ snippet:
--
@protocol PA;
@protocol PB;
@class NSArray<ObjectType>;
typedef int some_t;
id<PA> FA(NSArray<id<PB>> *h, some_t group);
--
This would hit an assertion in the parser after generating an annotation token
while trying to update the token cache:
Assertion failed: (CachedTokens[CachedLexPos-1].getLastLoc() == Tok.getAnnotationEndLoc() && "The annotation should be until the most recent cached token")
...
7 clang::Preprocessor::AnnotatePreviousCachedTokens(clang::Token const&) + 494
8 clang::Parser::TryAnnotateTypeOrScopeTokenAfterScopeSpec(bool, bool, clang::CXXScopeSpec&, bool) + 1163
9 clang::Parser::TryAnnotateTypeOrScopeToken(bool, bool) + 361
10 clang::Parser::isCXXDeclarationSpecifier(clang::Parser::TPResult, bool*) + 598
...
The cached preprocessor token in this case is:
greatergreater '>>' Loc=<testcase.mm:7:24>
while the annotation ("NSArray<id<PB>>") ends at "testcase.mm:7:25", hence the
assertion.
Properly update the CachedTokens during template parsing to contain
two greater tokens instead of a greatergreater.

These sets perform linear searching in small mode so it is never a good
idea to use SmallSize/N bigger than 32.

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.

The list of class properties is saved in
Old ABI: category->class_properties (category->size will be updated as well)
New ABI: category->class_properties (a flag in objc_image_info to indicate
whether or not the list of class properties is present)

We already do this for case splits introduced as a result of defensive null
checks in functions and methods, so do the same for function-like macros.

- Include the position of the argument on which the nullability is violated
- Differentiate between a 'method' and a 'function' in the message wording
- Test for the error message text in the tests
- Fix a bug with setting 'IsDirectDereference' which resulted in regular dereferences assumed to have call context.

The test is failing on SystemZ since different IR is being
generated due to platform ABI differences. Add a target triple.

Summary:
This is necessary to prevent llvm from generating stacksave intrinsics
around this alloca. NVVM doesn't have a stack, and we don't handle said
intrinsics.

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.

Frontend can emit errors when releaseing the Builder. If there are errors before
or when releasing the Builder, we reset the module to stop here before invoking
the backend.
Before this commit, clang will continue to invoke the backend and backend can
crash.

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.
