This seems like redundant leftovers from r142288 - exposing
TargetData::parseSpecifier to LLParser - which got reverted. Removes
redunant td != NULL checks in parseSpecifier, and simplifies the
interface to parseSpecifier and init.

non-trivial if they would not call a move operation, even if they would in fact
call a trivial copy operation. A proper fix is to follow, but this small
directed fix is intended for porting to the 3.2 release branch.

the related comma pasting extension.
In certain cases, we used to get two diagnostics for what is essentially one
extension. This change suppresses the first diagnostic in certain cases
where we know we're going to print the second diagnostic. The
diagnostic is redundant, and it can't be suppressed in the definition
of the macro because it points at the use of the macro, so we want to
avoid printing it if possible.
The implementation works by detecting constructs which look like comma
pasting at the time of the definition of the macro; this information
is then used when the macro is used. (We can't actually detect
whether we're using the comma pasting extension until the macro is
actually used, but we can detecting constructs which will be comma
pasting if the varargs argument is elided.)

This corrects the mangling and linkage of classes (& their member functions) in
cases like this:
struct foo {
struct {
void func() { ... }
} x;
};
we were accidentally giving this nested unnamed struct 'no' linkage where it
should've had the linkage of the outer class. The mangling was incorrecty too,
mangling as TU-wide unnamed type mangling of $_X rather than class-scoped
mangling of UtX_.
This also fixes -Wunused-member-function which would incorrectly diagnose
'func' as unused due to it having no linkage & thus appearing to be TU-local
when in fact it might be correctly used in another TU.
Similar mangling should be applied to function local classes in similar cases
but I've deferred that for a subsequent patch.

positions of Objective-C methods.
It is possible to recover a lot of type information about
Objective-C methods from the reflective metadata for their
implementations. This information is not rich when it
comes to struct types, however, and it is not possible to
produce a type in the debugger's round-tripped AST which
will really do anything useful during type-checking.
Therefore we allow __unknown_anytype in these positions,
which essentially disables type-checking for that argument.
We infer the parameter type to be the unqualified type of
the argument expression unless that expression is an
explicit cast, in which case it becomes the type-as-written
of that cast.

(There's a minor ObjC++ language change here: given that we can't save the
value, the type of the assignment expression is void in such cases.)
