PR middle-end/20622
* cgraph.h (struct cgraph_varpool_node): Add alias field.
* cgraph.c (cgraph_varpool_assemble_pending_decls): Don't call
assemble_variable on aliases.
* varasm.c (assemble_alias): Set node->alias.
* toplev.c (wrapup_global_declarations): Don't call
rest_of_decl_compilation on aliases again.
* gcc.dg/alias-7.c: New test.
