When all the arguments of a template are elided, print "A<...>" instead of
"A<[2 * ...]>". Also remove comment fragment that means nothing.

RecursiveASTVisitor::TraverseFunctionHelper() traverses a function's
ParmVarDecls by going to the function's getTypeSourceInfo if it exists, and
`DEF_TRAVERSE_TYPELOC(FunctionProtoType` then goes to the function's
ParmVarDecls.
For a function template that doesn't have parameters that explicitly depend on
the template parameter, we used to be clever and not build a new
TypeSourceInfo. That meant that when an instantiation of such a template is
visited, its TypeSourceInfo would point to the ParmVarDecls of the template,
not of the instantiation, which then confused clients of RecursiveASTVisitor.
So don't be clever for function templates that have parameters, even if none of
the parameters depend on the type.
Fixes PR26257.

Patch by H.J. Lu
```
typedef unsigned int gcc_word __attribute__((mode(word)));
```
and
```
typedef unsigned int gcc_unwind_word __attribute__((mode(unwind_word)));
```
define the largest unsigned integer types which can be stored in a
general purpose register, which may not be the pointer type. For x32,
they aren't pointer nor unsigned long. We should
1. Make getUnwindWordWidth and getRegisterWidth virtual,
2. Override them for x32, similar to hasInt128Type.
3. Use getRegisterWidth for __attribute__((mode(word)));
This fixes PR 24706.

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

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.

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.

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.
