Peter Wang eeec14a8b1 Replace the implementations of (version) hash tables by separate chaining hash

Branches: main

Replace the implementations of (version) hash tables by separate chaining hash
tables.  The old open addressing scheme was broken in the presence of deletes.
Fixes bug #68.

library/hash_table.m:
library/version_hash_table.m:
	As above.

	We no longer use double hashing in case of a hash collision, so hash
	predicates only need to return one value now.

	Add fold with predicate arguments.

library/array.m:
	Add array.foldl for a predicate argument.

	Add array.foldl2 with a unique state pair.

library/version_array.m:
	Add version_array.foldl for a predicate argument.

compiler/make.m:
compiler/make.program_target.m:
compiler/make.util.m:
library/robdd.m:
	Conform to change in hashing predicates.

deep_profiler/dense_bitset.m:
	Add module qualifier to avoid ambiguity.

tests/hard_coded/Mmakefile:
tests/hard_coded/hash_table_delete.exp:
tests/hard_coded/hash_table_delete.m:
tests/hard_coded/hash_table_test.exp:
tests/hard_coded/hash_table_test.m:
tests/hard_coded/version_hash_table_delete.exp:
tests/hard_coded/version_hash_table_delete.m:
tests/hard_coded/version_hash_table_test2.exp:
tests/hard_coded/version_hash_table_test2.m:
	Add new test cases.

tests/hard_coded/hash_bug.m:
tests/hard_coded/hash_init_bug.m:
tests/hard_coded/version_hash_table_test.m:
	Conform to change in hashing predicates.

NEWS:
	Document additions.
