Log:
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.
