  p->~T()

when p is a pointer to a scalar type. 

We don't currently diagnose errors when pseudo-destructor expressions
are used in any way other than by forming a call.

If the alignment of the chosen field in a union is greater than the alignment of the union, we need to use a packed LLVM struct. Fixes <rdar://problem/7184250>.

Fixed bug introduced in r79900 where FreeBSD was turned into NetBSD, transposing the ABIs and breaking both platforms.

Fix an assertion when initializing a union using a member initializer. (We weren't casting from the union type to the initializer type correctly).

source range. We'll do the same thing with explicitly-specified
template arguments, assuming I don't flip-flop again.

also be adding explicit template arguments as an additional

API for copying GC'able aggregates (Next runtime only).

  x->Base::f()

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.

When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

but not yet necessarily perfectly consistent with gcc.  Also addressed
Doug and John's comments.

llvm-svn: 80137

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.
