If the values from the body were in progress of being returned via
unknown-values convention we would (try to) pop the pointers while
the last callee stack frame (where the values to be returned are)
is still on the stack. In many cases this was harmless, as the correct
SP was restored soon enough, but there were bad interactions as well.
* Solution: instead of explicitly pushing pointers, use a LET to
add binding to the current stack frame for the objects, and further
use a magic TOUCH-OBJECT function implemented with an empty VOP
to trick the compiler into keeping the variables live till the end
of the body.

1.0.10.14: remove locking and gc inhibition from hash-tables, power of 2 sizes
This commit removes a bunch of bottlenecks from the hash-table
implementation. It speeds up GETHASH, (SETF GETHASH) and
REMHASH by a factor of 2-4x (on platforms with a real
WITH-PINNED-OBJECTS) depending on the operation. On the flip
side, no automatic locking is done on tables any more, so
multi-threaded applications must do their own locking. (The
locking done by SBCL was always just an implementation detail,
not a part of the external interface). By popular demand it's
also still safe to have multiple readers on the same table
without locking.
Originally GCs were inhibited during most hash-table
operations for two reasons. To prevent the GC from rehashing a
table while a Lisp-side operation is going on, and to prevent
the GC from moving the key after the hash-value has been
calculated.
More recently, most hash-tables operations have acquired a
lock on the table in order to prevent two concurrent writers
from corrupting the chains. While it's never been the intent
for the standard data structures to be automatically
thread-safe in SBCL, this locking had to be done since corrupt
tables could lead to infinite GC loops.
Both the locking and the without-gcing are expensive
operations relative to the total cost of a hash-table lookup.
This commit removes both the gc inhibition and the locks.
Additionally we switch to power of two table size, which
allows calculating a cheaper hash -> bucket with cheaper
operations than MOD.
* The GC no longer does the rehashing itself, but just marks
the hash-table as needing a rehash, which will then be done
Lisp-side when the table is next accessed. While it's
possible to find cases where the former behaviour has better
performance, they're very contrived.
* The hash-table operations that work on the chains now check
for loops in the chains, and signal an error if one is found.
* The hash-table operations now pin the key before calculating
the hash value (needed for EQ-based hash functions).
* Add a GC epoch value that GETHASH can use to check whether
a GC happened during the lookup. This is needed since another
thread calling GETHASH on the same table might have caused it
to be rehashed.
* Kill the old MUST-REHASH vector header, and replace it with a
slot in the HASH-TABLE structure. The overloading of the header
caused missed rehashings when both the GC and %%PUTHASH modified
it at the same time.
* Switch to power of two table sizes, with a slightly more complex
hash value -> bucket calculation than just taking the low bits,
which in many cases have a very skewed distribution for the existing
SBCL hash functions. Still a lot faster than using MOD.
* Leave in locking and GC inhibition during rehashing (needed to
allow multiple readers to coexist) and for weak hash-tables
(they need some GC support, and the code is much simpler when
all of the logic is in the GC instead of interleaved in the GC and
Lisp-side). Neither of these cases is performance critical.
