Share hash table test structs
This saves several words in the hash table object at the cost of an
indirection at runtime. This seems to be a gain in overall
performance.
FIXME: We cache hash test objects in a rather clumsy way. A better
solution is sought.
* src/lisp.h (struct Lisp_Hash_Table): Use a pointer to the test
struct. All references adapted.
* src/alloc.c (garbage_collect):
* src/fns.c (struct hash_table_user_test, hash_table_user_tests)
(mark_fns, get_hash_table_user_test): New state for caching test
structs, and functions managing it.
