Significantly speed up verifiers for a cgraph_node with many clones.
2019-03-07 Martin Liska <mliska@suse.cz>
* cgraph.c (cgraph_node::verify_node): Verify with a neighbour
which is equivalent to searching for this in clones chain.
* symtab.c (symtab_node::verify_base): Similarly compare ASM
names with a neighbour and special case first node in a chain.
