between C++ overloading (which handled scoped enumerations correctly)
and C binary operator type-checking (which didn't).

the overloading of member and non-member functions results in arity
mismatches that don't fit well into our overload-printing scheme. This
only happens for invalid code (which breaks the arity invariants for
these cases), so just suppress the diagnostic rather than inventing
anything new. Fixes <rdar://problem/9222009>.

KVC completions, to eliminate duplicates. Fixes <rdar://problem/9162207>.

Increase robustness of the delegating constructor cycle detection
mechanism. No more infinite loops on invalid or logic errors leading to
false results. Ensure that this is maintained correctly accross
serialization.

information. Rather than looking at the declaration kind to figure out
what TypeLoc to build, look at the type; it makes so much more
sense. Fixes <rdar://problem/9086649>.

We can use this to produce nice diagnostics (and try to fixit-and-recover) in
various cases where we might see "MyFunction" instead of "MyFunction()". The
changes in SemaExpr are an example of how to use isExprCallable.

Ivar offsets for synthesized ivars are wrong, which could end up with a large
number of dirty pages because of ivar fixups at runtime. When we pack all of the
synthesized ivars into the same section, it limits the number of dirty pages
created. Place them in the "__DATA,__objc_ivar" section.

Adjacent bit fields are packed into the same 1-, 2-, or
4-byte allocation unit if the integral types are the same

Like in r126648, provide (empty) default implementation for pure virtual getMemoryBufferSizes(). Not all use cases have meaningful implementations.

This is more efficient as it's all done at once at the end of the TU.
This could still get expensive, so a flag is provided to disable it. As
an added bonus, the diagnostics will now print out a cycle.
The PCH test is XFAILed because we currently can't deal with a note
emitted in the header and I, being tired, see no other way to verify the
serialization of delegating constructors. We should probably address
this problem /somehow/ but no good solution comes to mind.

if they match that production, i.e. if they're template type parameters
or decltypes (or, as an obvious case not yet described in the ABI document,
if they're template template parameters applied to template arguments).

tag, filter out those ambiguous names that we found if they aren't
within the declaration context where this newly-defined tag will be
visible.
This is basically a hack, because we really need to fix the lookup of
tag declarations in this case to not find things it
shouldn't. However, it's better than what we had before, and it fixes
<rdar://problem/9168556>.

the body of a delegating constructor call.
This means that the delegating constructor implementation should be
complete and correct, though there are some rough edges (diagnostic
quality with the cycle detection and using a deleted destructor).

parameters on the floor in certain cases:
class X {
template <typename T> friend typename A<T>::Foo;
};
This was parsed as a *non* template friend declaration some how, and
received an ExtWarn. Fixing the parser to actually provide the template
parameters to the freestanding declaration parse triggers the code which
specifically looks for such constructs and hard errors on them.
Along the way, this prevents us from trying to instantiate constructs
like the above inside of a outer template. This is important as loosing
the template parameters means we don't have a well formed declaration
and template instantiation will be unable to rebuild the AST. That fixes
a crash in the GCC test suite.
