Log Message:
ddb(4), crash(8): Make `show all locks' work without LOCKDEBUG.

Any lwp currently waiting for a _contended_ lock will now record a
pointer to that lock in struct lwp::l_ld_wanted, even without
LOCKDEBUG.  We can't tell who holds shared locks or spin locks, but we
can at least tell what lock a thread is waiting for when it's spinning
for a spin lock, and generally present the graph of current lock
dependencies reasonably well this way.
