The plan is to store a backpointer to the original decl within the generated
SRA variable, and use it for diagnostic purposes. For instance, in the case of
"a$i" we would be storing a pointer to the original INDIRECT_REF from which the
scalarized version was created. This is similar to what DannyB did with his
DECL_DEBUG_ALIAS_OF (http://gcc.gnu.org/ml/gcc-patches/2004-12/msg01883.html)
but I think vindex isn't free in all the entities SRA generates.
