        PR tree-optimization/26830

        * tree-ssa-copy.c (copy_prop_visit_assignment): Do not check loop
depth.
        (copy_prop_visit_stmt): Remove write-only variable ann.
        (init_copy_prop): Check variable loop depth here.  Do not simulate
        memory-tag and virtual operand PHIs except for store copy prop.
