        * tree-ssa-live.c (mark_all_vars_used): Add data argument,
        pass it to walk_tree.
        (mark_all_vars_used_1): Pass data through to mark_all_vars_used.
        When calling set_is_used on a VAR_DECL, if data is not NULL and
        its DECL_UID is in the bitmap, call mark_all_vars_used on its
        DECL_INITIAL after clearing the bit in bitmap.
        (remove_unused_locals): Adjust mark_all_vars_used callers.
        Instead of removing unused global vars from unexpanded_var_list
        immediately record them in bitmap, call mark_all_vars_used on
        all used global vars from unexpanded_var_list and only purge
        global vars that weren't found used even during that step.

        * gcc.dg/pr33645-1.c: New test.
        * gcc.dg/pr33645-2.c: New test.
        * gcc.dg/pr33645-3.c: New test.
