Since SSA names do leak into global tree data structures like
TYPE_SIZE or in this case GFC_DECL_SAVED_DESCRIPTOR because of
frontend bugs we have to be careful to wipe references to the
CFG when we deconstruct SSA form because we now do ggc_free that.

My recent patch that introduced push_using_decl_bindings didn't
handle USING_DECL redeclaration, therefore things broke. This
patch amends that. Note that I don't know if the other parts of
finish_nonmember_using_decl are needed (e.g. the binding->type
setting) -- I couldn't trigger it by any of my hand-made testcases.
Sorry for not thinking harder about redeclarations in the original
patch :(.

* dwarf2out.c (reset_indirect_string): Also reset indirect strings
with DW_FORM_line_strp form.
(prune_unused_types_update_strings): Don't add into debug_str_hash
indirect strings with DW_FORM_line_strp form.
(adjust_name_comp_dir): New function.
(dwarf2out_finish): Call it on CU DIEs after resetting
debug_line_str_hash.
