This saves a lot of memory and is quite sufficient. Hash functions
are adapted to produce a hash_hash_t eventually, which eliminates some
useless and information-destroying intermediate hash reduction steps.
We still use EMACS_UINT for most of the actual hashing steps before
producing the final value; this may be slightly wasteful on 32-bit
platforms with 64-bit EMACS_UINT.

Use key Qunbound instead of hash value hash_unused for free entries
Previously, free hash table entries were indicated by both hash value
hash_unused and key Qunbound; we now rely on the latter only.
This allows us to change the hash representation to one that does not
have an unused value.
* src/lisp.h (hash_unused): Remove.
All uses adapted to calling hash_unused_entry_key_p on the key instead.
The hash values for unused hash table entries are now undefined; all
initialisation and assignment to hash_unused has been removed.
The dumper uses a hash table to keep track of dumped objects but as
this clashes with the use of Qunbound for marking unused hash table
entries, don't dump that value at all. The symbol name is fixed up
after loading.
An alternative solution would be to use a different unique value for
unused entries.
* src/pdumper.c (dump_object_needs_dumping_p): Skip Qunbound.
(dump_vectorlike_generic): New function.
(pdumper_load): Call it.
The algorithms no longer use the rehash_threshold and rehash_size
float constants, but vary depending on size. In particular, the table
now grows faster, especially from smaller sizes.
The default size is now 0, starting empty, which effectively postpones
allocation until the first insertion (unless make-hash-table was
called with a positive :size); this is a clear gain as long as the
table remains empty. The first inserted item will use an initial size
of 8 because most tables are small.
* src/fns.c (std_rehash_size, std_rehash_threshold): Remove.
(hash_index_size): Integer-only computation.
(maybe_resize_hash_table): Grow more aggressively.
(Fhash_table_rehash_size, Fhash_table_rehash_threshold):

* src/lisp.h (DEFAULT_HASH_SIZE): New value.

* 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

Now hash_idx_t is a typedef for ptrdiff_t so there is no actual code
change, but this allows us to decouple the index width from the Lisp
word size.
* src/lisp.h (hash_idx_t): New typedef for ptrdiff_t.
(struct Lisp_Hash_Table): Use it for indices and sizes:
index, next, table_size, index_size, count and next_free.
All uses adapted.
Store hash values as integers instead of Lisp_Object
This improves typing, saves pointless tagging and untagging, and
prepares for further changes. The new typedef hash_hash_t is an alias
for EMACS_UINT, and hash values are still limited to the fixnum range.
We now use hash_unused instead of Qnil to mark unused entries.
* src/lisp.h (hash_hash_t): New typedef for EMACS_UINT.
(hash_unused): New constant.
(struct hash_table_test): `hashfn` now returns
hash_hash_t. All callers and implementations changed.
(struct Lisp_Hash_Table): Retype hash vector to an array of
hash_hash_t. All code using it changed accordingly.
(HASH_HASH, hash_from_key):
* src/fns.c (set_hash_index_slot, hash_index_index)
(hash_lookup_with_hash, hash_lookup_get_hash, hash_put):
(hash_lookup, hash_put): Retype hash value arguments
and return values. All callers adapted.
Use non-Lisp allocation for internal hash-table vectors
Using xmalloc for allocating these arrays is much cheaper than using
Lisp vectors since they are no longer marked or swept by the GC, and
deallocated much sooner. This makes GC faster and less frequent, and
improves temporal locality.
Zero-sized tables use NULL for their (0-length) vectors except the
index vector which has size 1 and uses a shared constant static vector
since it cannot be modified anyway. This makes creation and
destruction of zero-sized hash tables very fast; they consume no
memory outside the base object.
* src/lisp.h (struct Lisp_Hash_Table): Retype the index, next, hash
and key_and_value vectors from Lisp_Object to appropriately typed
arrays (although hash values are still stored as Lisp fixnums). Add
explicit table_size and index_size members. All users updated.

* src/alloc.c (process_mark_stack): Don't mark pure objects,

The profiler stored data being collected in Lisp hash tables but
relied heavily on their exact internal representation, which made it
difficult and error-prone to change the hash table implementation.
In particular, the profiler has special run-time requirements that are
not easily met using standard Lisp data structures: accesses and
updates are made from async signal handlers in almost any messy
context you can think of and are therefore very constrained in what
they can do.
The new profiler tables are designed specifically for their purpose
and are more efficient and, by not being coupled to Lisp hash tables,
easier to keep safe.
The old profiler morphed internal hash tables to ones usable from Lisp
and thereby made them impossible to use internally; now export_log
