* tree-ssa-alias.c (compute_flow_insensitive_aliasing): Make sure
subvars get marked properly in tags for grouping.
(add_pointed_to_var): Mark only actual pointed to
variables/subvars in addresses needed.
(create_overlap_variables_for): Clear call clobbered on original
variable.

addresable vars with subvars into list.
* tree-ssa.c (verify_ssa_name): Verify original is not used where
subvar should be.
