Bug is revealed by OID regress test on 64-bit platforms.

when using vendor cc, not gcc.

for Alpha gcc case.  For Alpha non-gcc case, replace use of
__INTERLOCKED_TESTBITSS_QUAD builtin with __LOCK_LONG_RETRY and
__UNLOCK_LONG.  The former does not execute an MB instruction and
therefore was guaranteed not to work on multiprocessor machines.
The LOCK_LONG builtins produce code that is the same in all essential
details as the gcc assembler code.

In theory we should always get EEXIST if there's a key collision, but
if the kernel code tests error conditions in a weird order, perhaps
EACCES or EIDRM could occur too.

been the supported and documented way to do this for a long time...

assume that TAS() will always succeed the first time, even if the lock
is known to be free.  Also, make sure that code will eventually time out
and report a stuck spinlock, rather than looping forever.  Small cleanups
in s_lock.h, too.

drivers.

The first fix fixes the PreparedStatement object to not allocate
unnecessary objects when converting native types to Stings.  The old
code used the following format:
        (new Integer(x)).toString()
whereas this can more efficiently be occompilshed by:
        Integer.toString(x);
avoiding the unnecessary object creation.

The second fix is to release some resources on the close() of a
ResultSet.  Currently the close() method on ResultSet is a noop.  The
purpose of the close() method is to release resources when the ResultSet
is no longer needed.  The fix is to free the tuples cached by the
ResultSet when it is closed (by clearing out the Vector object that
stores the tuples).  This is important for my application, as I have a
cache of Statement objects that I reuse.  Since the Statement object
maintains a reference to the ResultSet and the ResultSet kept references
to the old tuples, my cache was holding on to a lot of memory.

some other oddities.

for 64-bit platforms ...

1. Distinguish cases where a Datum representing a tuple datatype is an OID
from cases where it is a pointer to TupleTableSlot, and make sure we use
the right typlen in each case.
2. Make fetchatt() and related code support 8-byte by-value datatypes on
machines where Datum is 8 bytes.  Centralize knowledge of the available
by-value datatype sizes in two macros in tupmacs.h, so that this will be
easier if we ever have to do it again.
