Currently we return no results when completing inside of the brackets in
a 'char foo[]' declaration. Let the generic expression completion code
handle it instead. We could get fancier here (e.g. filter non-constant
expressions in contexts where VLAs are not allowed), but it's a strict
improvement over the existing version.

An optional nopartial can be placed after the platform name.
int bar() __attribute__((availability(macosx,nopartial,introduced=10.12))
When deploying back to a platform version prior to when the declaration was
introduced, with 'nopartial', Clang emits an error specifying that the function
is not introduced yet; without 'nopartial', the behavior stays the same: the
declaration is `weakly linked`.
A member is added to the end of AttributeList to save the location of the
'nopartial' keyword. A bool member is added to AvailabilityAttr.
The diagnostics for 'nopartial' not-yet-introduced is handled in the same way as
we handle unavailable cases.

While this won't help fix things like the bug that r260219 addressed, it
seems like good tidy up to have anyway.
(it might be nice if "makeArrayRef" always produced a MutableArrayRef &
let it decay to an ArrayRef when needed - then I'd use that for the
MutableArrayRefs in this patch)
If we had std::dynarray I'd use that instead of unique_ptr+size_t,
ideally (but then it'd have to be threaded down through the Preprocessor
all the way - no idea how painful that would be)

In the context where we break one tok::greatergreater into two
tok::greater in order to correctly update the cached tokens; update the
CachedTokens with two tok::greater only if ParseGreaterThanInTemplateList
clients asks to consume the last token. Otherwise we only need to add
one because the second is already added later on, as a not yet cached token.

a cast expression is not the operand of a cast expression itself, so if it's
parenthesized we need to form a ParenExpr not a ParenListExpr.

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.

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).

Summary:
Extend support in the map clause SEMA for the expressions supported in the OpenMP 4.5 specification, namely member expressions.
Fix some bugs in the previous implementation of SEMA related with expressions that do not consist of single variable references.
Fix bug in parsing when the expression in the map clause do not start with an identifier: accept any expression in the map clause and check for validity in SEMA instead of just ignoring it.

Support for the following OpenMP 4.5 restriction on 'target enter data' and 'target exit data':
- A map-type must be specified in all map clauses.
I have to save 'IsMapTypeImplicit' when parsing a map clause to support this constraint and for more informative error messages. This helps me support the following case:
#pragma omp target enter data map(r) // expected-error {{map type must be specified for '#pragma omp target enter data'}}
and distinguish it from:
#pragma omp target enter data map(tofrom: r) // expected-error {{map type 'tofrom' is not allowed for '#pragma omp target enter data'}}

An undecorated function designator implies taking the address of a function,
which is illegal in OpenCL. Implementing a check for this earlier to allow

OpenMP 4.0-3.1 supports the next format of ‘schedule’ clause: schedule(kind[, chunk_size])
Where kind can be one of ‘static’, ‘dynamic’, ‘guided’, ‘auto’ or ‘runtime’.
OpenMP 4.5 defines the format: schedule([modifier [, modifier]:]kind[, chunk_size])
Modifier can be one of ‘monotonic’, ‘nonmonotonic’ or ‘simd’.
