for char. This fixes a miscompmilation of XULRunner, PR8856.

packs, e.g.,
template<typename T, unsigned ...Dims> struct multi_array;
along with semantic analysis support for finding unexpanded non-type
template parameter packs in types, expressions, and so on.
Template instantiation involving non-type template parameter packs
probably doesn't work yet. That'll come soon.

pack expansions, e.g. given
template<typename... Types> struct tuple;
template<typename... Types>
struct tuple_of_refs {
typedef tuple<Types&...> types;
};
the type of the "types" typedef is a PackExpansionType whose pattern
is Types&.
This commit introduces support for creating pack expansions for
template type arguments, as above, but not for any other kind of pack
expansion, nor for any form of instantiation.

space better. Remove this reference. To make that work, change some APIs
(most importantly, getDesugaredType()) to take an ASTContext& if they
need to return a QualType. Simultaneously, diminish the need to return a
QualType by introducing some useful APIs on SplitQualType, which is
just a std::pair<const Type *, Qualifiers>.

This is needed for Neon types when it is most natural to define them in terms
of a typedef. For example, Neon poly8_t is a typedef for "signed char", and
we want to define polynomial vectors as vectors of that typedef. Without this
change, the result will be a generic GCC-style vector. I think this is safe
for other vector types as well, but I would appreciate a review of this.

NEON vector types need to be mangled in a special way to comply with ARM's ABI,
similar to some of the AltiVec-specific vector types. This patch is mostly
just renaming a bunch of "AltiVecSpecific" things, since they will no longer
be specific to AltiVec. Besides that, it just adds the new "NeonVector" enum.

mangler. Now member functions and pointers thereof have their calling
convention mangled as __thiscall if they have the default CC (even though,
they technically still have the __cdecl CC).

abstractions (e.g., TemplateArgumentListBuilder) that were designed to
support variadic templates. Only a few remnants of variadic templates
remain, in the parser (parsing template type parameter packs), AST
(template type parameter pack bits and TemplateArgument::Pack), and
Sema; these are expected to be used in a future implementation of
variadic templates.
But don't get too excited about that happening now.

or dependent specializations, rip apart the dependent name/dependent
specialization to recanonicalize its pieces, because
nested-name-specifiers store "dependent-type::identifier" differently
than types do. Fixes PR7419.

getCanonicalType() to make sure that the type we got back is actually
canonical. This is the case for most types, which always build a
canonical type when given canonical components. However, some types that
involve expressions in their canonicalization (e.g., array types with
dependent sizes) don't always build canonical types from canonical
components, because there is no such thing as a "canonical"
expression. Therefore, we do this extra mapping to ensure that the
canonical types we store are actually canonical.

its initial creation/deserialization and store the changes in a chained PCH.
The idea is that the AST entities call methods on the ASTMutationListener to give notifications
of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes
of the updated entity. WIP

unless it's a non-packed field, in which case it can only increase the
alignment. [[align]] effectively works the same way for well-formed code
(because it's ill-formed for [[align]] to decrease alignment ever).
