I'm reasonably sure my implementation is correct, but it would be nice if
someone could double-check.

Clang's support for weakref is now better than llvm-gcc's :-)
We don't introduce a new symbol and we correctly mark undefined references weak only if there is no
definition or regular undefined references in the same file.

we now may have identical states with different analysis context.
Set the right AnalysisContext in state when entering and leaving a callee.
With both of the above changes, we can pass the test case.

nested-name-specifier. For example, this allows member access in
diamond-shaped hierarchies like:
struct Base {
void Foo();
int Member;
};
struct D1 : public Base {};
struct D2 : public Base {};
struct Derived : public D1, public D2 { }
void Test(Derived d) {
d.Member = 17; // error: ambiguous cast from Derived to Base
d.D1::Member = 17; // error: okay, modify D1's Base's Member
}
Fixes PR5820 and <rdar://problem/7535045>. Also, eliminate some
redundancy between Sema::PerformObjectMemberConversion() and
Sema::PerformObjectArgumentInitialization() -- the latter now calls
the former.

fix a code gen crash. This is WIP as not
all ABI cases are covered (there is a FIXME to
this effect). Fixes radar 7696748.

lookup path that does *not* pass through the hiding subobject (C++
[class.member.lookup]p6). Fixes PR6462.

declarations after the member has been explicitly specialized. We already
did this after explicit instantiation definitions; not doing it for
declarations meant that subsequent definitions would see a previous
member declaration with specialization kind "explicit instantiation decl",
which would then happily get overridden.

cast syntax over to using the new initialization code. Fixes PR6457.

for the purposes of parsing default arguments. In effect, we would
re-introduce the parameter with a default argument N times (where N is
the number of parameters preceding the parameter with a default
argument). This showed up when a defaulted parameter of a member
function of a local class shadowed a parameter of the enclosing
function. Fixes PR6383.

*not* entering the context of the nested-name-specifier. This was
causing us to look into an uninstantiated template that we shouldn't
look into. Fixes PR6376.

category. Use this in a few places to eliminate unnecessary TST cases and
do some future-proofing. Provide terrible manglings for typeof. Mangle
decltype with some hope of accuracy.
Our manglings for some of the cases covered in the testcase are different
from gcc's, which I've raised as an issue with the ABI list.

which has the label map, switch statement stack, etc. Previously, we
had a single set of maps in Sema (for the function) along with a stack
of block scopes. However, this lead to funky behavior with nested
functions, e.g., in the member functions of local classes.
The explicit-stack approach is far cleaner, and we retain a 1-element
cache so that we're not malloc/free'ing every time we enter a
function. Fixes PR6382.
Also, tweaked the unused-variable warning suppression logic to look at
errors within a given Scope rather than within a given function. The
prior code wasn't looking at the right number-of-errors count when
dealing with blocks, since the block's count would be deallocated
before we got to ActOnPopScope. This approach works with nested
blocks/functions, and gives tighter error recovery.
