* c-decl.c (finish_decl): Also set DECL_HARD_REGISTER for global
register variables.
* tree-ssa-sccvn.c (vn_reference_op_eq): Disregard differences
in type qualification here ...
(copy_reference_ops_from_ref): ... not here.
(vn_reference_lookup_3): ... or here.
(copy_reference_ops_from_ref): Record decl bases as MEM[&decl].
(vn_reference_lookup): Do the lookup with a valueized ao-ref.
