Make cgraph_edge::uid really unique.
2018-06-08 Martin Liska <mliska@suse.cz>
* cgraph.c (symbol_table::create_edge): Always assign a new
unique number.
(symbol_table::free_edge): Do not recycle numbers.
* cgraph.h (cgraph_edge::get): New method.
* symbol-summary.h (symtab_removal): Use it.
(symtab_duplication): Likewise.
(call_summary::hashable_uid): Remove.
