Implement clang support for indirect branch and address of label
using the new LLVM support for this. This is temporarily hiding
behind horrible and ugly #ifdefs until the time when the optimizer
is stable (hopefully a week or so). Until then, lets make it "opt in" :)

Eliminate QualifiedDeclRefExpr, which captured the notion of a
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g.,

Eliminate QualifiedDeclRefExpr, which captured the notion of a
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g.,

namespace N { int i; }
int j = N::i;

Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.

Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

Teach sema and codegen about the difference between address of labels,
which is a common idiom to improve PIC'ness of code using the addr of
label extension. This implementation is a gross hack, but the only other
alternative would be to teach evalutate about this horrid combination.
While GCC allows things like "&&foo - &&bar + 1", people don't use this
in practice. This implements PR5131.

When building constant structs, check if the resulting LLVM struct will be bigger than the record layout size and use a packed struct if that's the case. Fixes PR5108.

Make address-space qualification work correctly for compound literals.
Issue reported on cfe-dev.

Also fixed the code to use isConstant to determine whether to generate a
constant global, to be consistent with CodeGenModule. This probably
needs to be refactored to deal with C++, though.
