CGExprAgg isn't really using it (it's an if around a FIXME), and the
code that might go there should really be checking the LLVM values,
not the AST value.

I'm not exactly sure why the DeadStores pass cares if the value is
constant; maybe it should just be checking for zero and other common
"dummy" initializations?
