particular issue was the cause of the Boost.Interprocess failures, and
in general will lead to horrendous, hard-to-diagnose miscompiles. The
assertion itself has survives self-host and a full Boost build, so we
are close to eradicating this problem in C++.

Note that the assertion is *not* turned on for Objective-C++, where we
still have problems with introducing memcpy's of non-POD class
types. That part of the assertion will go away as soon as we fix the
known issues in Objective-C++.

subobject. Previously, we could only properly bind to a base class
subobject while extending the lifetime of the complete object (of a
derived type); for non-static data member subobjects, we could memcpy
(!) the result and bind to that, which is rather broken.

Now, we pull apart the expression that we're binding to, to figure out
which subobject we're accessing, then construct the temporary object
(adding a destruction if needed) and, finally, dig out the subobject
we actually meant to access.

This fixes yet another instance where we were memcpy'ing rather than
doing the right thing. However, note the FIXME in references.cpp:
there's more work to be done for binding to subobjects, since the AST
is incorrectly modeling some member accesses in base classes as
lvalues when they are really rvalues.

pipeline stall. It's useful for targets like ARM cortex-a8. NEON has a lot
of long latency instructions so a strict register pressure reduction
scheduler does not work well.
Early experiments show this speeds up some NEON loops by over 30%.

class type (that uses a return slot), pass the return slot to the
callee directly rather than allocating new storage and trying to copy
the object. This appears to have been the cause of the remaining two
Boost.Interprocess failures.

  - Use isRecordType() rather than isa<RecordType>(), so that we see

instead of new[]'d.  This greatly reduces the number of new[]'s, and guess what, 
they were all leaked.

This adds a fixme in this hunk:

   unsigned NumPackArgs = NumFlatArgs - PackBeginIndex;
+  // FIXME: NumPackArgs shouldn't be negative here???
   if (NumPackArgs)
-    PackArgs = &FlatArgs[PackBeginIndex];
+    PackArgs = FlatArgs.data()+PackBeginIndex;

where test/SemaTemplate/variadic-class-template-2.cpp is accessing the vector
out of range and NumPackArgs is negative.  I assume variadic template args are
completely hosed.
