patch I am testing

Patch for both issues.  We shouldn't equate the BLOCK to concrete instance DIEs
we create.  And we should attach abstract origins to the concrete instance
BLOCKs (origin == stmt, see set_decl_origin_self - which I hoped to get rid of
at some point).

Slightly nicer solution would be to go for TREE_DIE_REF in DECL_ABSTRACT_ORIGIN
refering to the abstract DIEs we created for a decl.  I'll give that a try
anyways.
