hash-table.h: support non-zero empty values in empty_slow (v2)

gcc/cp/ChangeLog:
* cp-gimplify.c (source_location_table_entry_hash::empty_zero_p):
New static constant.
* cp-tree.h (named_decl_hash::empty_zero_p): Likewise.
(struct named_label_hash::empty_zero_p): Likewise.
* decl2.c (mangled_decl_hash::empty_zero_p): Likewise.

gcc/ChangeLog:
* attribs.c (excl_hash_traits::empty_zero_p): New static constant.
* gcov.c (function_start_pair_hash::empty_zero_p): Likewise.
* graphite.c (struct sese_scev_hash::empty_zero_p): Likewise.
* hash-map-tests.c (selftest::test_nonzero_empty_key): New selftest.
(selftest::hash_map_tests_c_tests): Call it.
* hash-map-traits.h (simple_hashmap_traits::empty_zero_p):
New static constant, using the value of = H::empty_zero_p.
(unbounded_hashmap_traits::empty_zero_p): Likewise, using the value
from default_hash_traits <Value>.
* hash-map.h (hash_map::empty_zero_p): Likewise, using the value
from Traits.
* hash-set-tests.c (value_hash_traits::empty_zero_p): Likewise.
* hash-table.h (hash_table::alloc_entries): Guard the loop of
calls to mark_empty with !Descriptor::empty_zero_p.
(hash_table::empty_slow): Conditionalize the memset call with a
check that Descriptor::empty_zero_p; otherwise, loop through the
entries calling mark_empty on them.
* hash-traits.h (int_hash::empty_zero_p): New static constant.
(pointer_hash::empty_zero_p): Likewise.
(pair_hash::empty_zero_p): Likewise.
* ipa-devirt.c (default_hash_traits <type_pair>::empty_zero_p):
Likewise.
* ipa-prop.c (ipa_bit_ggc_hash_traits::empty_zero_p): Likewise.
(ipa_vr_ggc_hash_traits::empty_zero_p): Likewise.
* profile.c (location_triplet_hash::empty_zero_p): Likewise.

* tree-vectorizer.h
(default_hash_traits<scalar_cond_masked_key>::empty_zero_p):
Likewise.
