After the previous patches in the series, there are three remaining hash traits that use the key to represent empty and deleted entries. This patch makes them use simple_hashmap_traits.
gcc/ * ipa-icf.h (symbol_compare_hash): New class. (symbol_compare_hashmap_traits): Use it. * mem-stats.h (mem_alloc_description::mem_location_hash): New class. (mem_alloc_description::mem_alloc_hashmap_traits): Use it. (mem_alloc_description::reverse_mem_map_t): Remove redundant default_hashmap_traits. * sanopt.c (sanopt_tree_triplet_hash): New class. (sanopt_tree_triplet_map_traits): Use it.
