Add a new 'type_visibility' attribute to allow users to
control the visibility of a type for the purposes of RTTI
and template argument restrictions independently of how
visibility propagates to its non-type member declarations.
Also fix r175326 to not ignore template argument visibility
on a template explicit instantiation when a member has
an explicit attribute but the instantiation does not.
The type_visibility work is rdar://11880378

Fix an old (2009) FIXME:
// FIXME: This needs to happen before we merge declarations. Then,
// let attribute merging cope with attribute conflicts.
This was already being done for variables, but for functions we were merging
then first and then applying the attributes. To avoid duplicating merging
logic, some of the helpers in SemaDeclAttr.cpp become methods that can
handle merging two attributes in one decl or inheriting attributes from one
decl to another.
With this change we are now able to produce errors for variables with
incompatible visibility attributes or warn about unused dllimports in
variables.
This changes the attribute list iteration back to being in reverse source
code order, as that matches what decl merging does and avoids differentiating
the two cases is the merge*Attr methods.

Process attributes in the order they appear in the source code. This make clang
match gcc behavior for two conflicting visibilities in the same decl. It also
makes handling of dllimport/dllexport more natural.
As a bonus we now warn on the dllimport in
void __attribute__((dllimport)) foo13();
void __attribute__((dllexport)) foo13();
as does gcc.

Walk the decls looking for the last one that has an attribute. We do have to walk
them, otherwise we cannot produce an error for both
struct HIDDEN test4; // canonical
struct test4;
struct DEFAULT test4;
and
struct test5; // canonical
struct HIDDEN test5;
struct DEFAULT test5;

Extend the error about incompatible visibility attributes in different
decls to work on function templates specializations.

Reject cases like
struct __attribute__((visibility("hidden"))) a;
struct __attribute__((visibility("default"))) b;
which gcc already rejects.

Complain about attempts to use 'protected' visibility on targets
like Darwin that don't support it. We should also complain about
invalid -fvisibility=protected, but that information doesn't seem
to exist at the most appropriate time, so I've left a FIXME behind.
