When the type being diffed is a type alias, and the orginal type is not a
templated type, then there will be no unsugared TemplateSpecializationType.
When this happens, exit early from the constructor. Also add assertions to
the other iterator accessor to prevent the iterator from being used.

Fixes https://llvm.org/bugs/show_bug.cgi?id=27129 which is crash involving type
aliases and template type diffing. Template arguments for type aliases and
template arguments for the underlying desugared type may not have one-to-one
relations, which could mess us the attempt to get more information from the
desugared type. For type aliases, ignore the iterator over the desugared type.

1) Print qualifiers for templates with zero arguments
2) Add a few more tests for the template type diffing refactoring.
Specifically, PR24587 has been fixed and has a test case from
http://reviews.llvm.org/D15384
3) Adds asserts to check the DiffTree is in correct state when moving nodes
4) Rename the field FromType and ToType since it is heavily used within
member functions.

Remove an old assertion that does not hold. It is possible for a template
argument to be a declaration in one instantiation and an integer in another.
Create two new diff kinds for these (decl vs int and int vs decl).

Save the integer type when diffing integers in template type diffing. When
integers are different sizes, print out the type along with the integer value.
Also with the type information, print true and false instead of 1 and 0 for
boolean values.

If available, use the canonical template argument to fill in information for
template type diffing instead of attempting to special case and evaluate Expr's
for the value. Since those are the values used in template instantiation,
we don't have to worry about difference between our evaluator and theirs. Also
move the nullptr template arguments from DiffKind::Expression to
DiffKind::Declaration and allow DiffKind::Declaration to set an Expr. The only
effect that should result is that a named nullptr will show up as
'ptr aka nullptr' in diagnostics.

Modify the TSTiterator to have two internal iterators, which will walk
the provided sugared type and the desugared type. This will provide better

1) Instead of using pairs of From/To* fields, combine fields into a struct
TemplateArgInfo and have two in each DiffNode.
2) Use default initialization in DiffNode so that the constructor shows the
only field that is initialized differently on construction.
3) Use Set and Get functions per each DiffKind to make sure all fields for the
diff is set. In one case, the Expr fields were not set.
4) Don't print boolean literals for boolean template arguments. This prevents
printing 'false aka 0'
Only #3 has a functional change, which is reflected in the test change.

Summary:
This change adds support for `__builtin_ms_va_list`, a GCC extension for
variadic `ms_abi` functions. The existing `__builtin_va_list` support is
inadequate for this because `va_list` is defined differently in the Win64
ABI vs. the System V/AMD64 ABI.
Depends on D1622.

After r244870 flush() will only compare two null pointers and return,
doing nothing but wasting run time. The call is not required any more
as the stream and its SmallString are always in sync.

Desugar doesn't necessarily initialize ShouldAKA, but as of r241542 it
may read it. Fix the misuse of the API and initialize this before
passing it in.

The __kindof type qualifier can be applied to Objective-C object
(pointer) types to indicate id-like behavior, which includes implicit
"downcasting" of __kindof types to subclasses and id-like message-send
behavior. __kindof types provide better type bounds for substitutions
into unspecified generic types, which preserves more type information.

Objective-C type arguments can be provided in angle brackets following
an Objective-C interface type. Syntactically, this is the same
position as one would provide protocol qualifiers (e.g.,
id<NSCopying>), so parse both together and let Sema sort out the
ambiguous cases. This applies both when parsing types and when parsing
the superclass of an Objective-C class, which can now be a specialized
type (e.g., NSMutableArray<T> inherits from NSArray<T>).
Check Objective-C type arguments against the type parameters of the
corresponding class. Verify the length of the type argument list and
that each type argument satisfies the corresponding bound.
Specializations of parameterized Objective-C classes are represented
in the type system as distinct types. Both specialized types (e.g.,
NSArray<NSString *> *) and unspecialized types (NSArray *) are
represented, separately.

Fix for PR22017. Integer template arguments are automatically bit extended to
the size of the integer type. In template diffing, evaluated expressions were
not having their results extending, leading to comparing two APSInt's with
different widths. Apply the proper bit extending when evaluating template
arguments. This mainly affected bool template arguments.

and only update the orginal list on a valid arugment list. When checking an
individual expression template argument, and conversions are required, update
the expression in the template argument. Since template arguments are
speculatively checked, the copying of the template argument list prevents
updating the template arguments when the list does not match the template.
Additionally, clean up the integer checking code in the template diffing code.
The code performs unneccessary conversions from APSInt to APInt.
Fixes PR21758.
This essentially reverts r224770 to recommits r224667 and r224668 with extra
changes to prevent the template instantiation problems seen in PR22006.
A test to catch the discovered problem is also added.

logic.
In one place we would try to check for the difference between integers
even if we were missing one of the integers. This would eventually end
up reading uninitialized data out of the APSInt objects. The fix is to
short circuit the sameness test when we don't have integers on both
sides.
This fixes a test failure I was seeing with MSan. Not sure whether other
bots were seeing it or not, but yay MSan. In particular the feature to
very carefully track origins back through stores throughout the program
was invaluable.

Reverts most of the changes from r168005. Since template arguments have proper
conversions now, no extending of integers is needed. Further, since the
integers are the correct size now, use APSInt::operator== instead of
APSInt::hasSameValue since operator== will check the size and signness match.
Prior to one comparison of APSInt's, check that both are valid. Previous, one
could be uninitialized. Also changed APInt to APSInt in GetInt. This
occassionally produced a sign flip, which will now be caught by operator==.

When a non-type template argument expression needs a conversion to change it
into the argument type, preserve that information by remaking the
TemplateArgument with an expression that has those conversions. Also a small
fix to template type diffing to handle the extra conversions in some cases.

Add driver and frontend support for the GCC -Wframe-larger-than=bytes warning.
This is the first GCC-compatible backend diagnostic built around LLVM's
reporting feature.
This commit adds infrastructure to perform reverse lookup from mangled names
emitted after LLVM IR generation. We use that to resolve precise locations and
originating AST functions, lambdas or block declarations to produce seamless
codegen-guided diagnostics.
An associated change, StringMap now maintains unique mangled name strings
instead of allocating copies. This is a net memory saving in C++ and a small
hit for C where we no longer reuse IdentifierInfo storage, pending further
optimisation.

We never aka vector types because our attributed syntax for it is less
comprehensible than the typedefs. This leaves the user in the dark when
the typedef isn't named that well.
Example:
v2s v; v4f w;
w = v;
The naming in this cases isn't even that bad, but the error we give is
useless without looking up the actual typedefs.
t.c:6:5: error: assigning to 'v4f' from incompatible type 'v2s'
Now:
t.c:6:5: error: assigning to 'v4f' (vector of 4 'float' values) from
incompatible type 'v2s' (vector of 2 'int' values)
We do this for all diagnostics that print a vector type.

Summary:
In general, this type node can be used to represent any type adjustment
that occurs implicitly without losing type sugar. The immediate use of
this is to adjust the calling conventions of member function pointer
types without breaking template instantiation.
