fix misoptimization of TRUNCATE
Reported by Eric Marsden on sbcl-devel 2011-12-01.
"illegal instruction on PowerPC"
We check for result type being a VALUES-TYPE-P when deciding if to compute
the second value for TRUNCATE or not -- but *WILD-TYPE* isn't a values type.
Make VALUES-TYPE-P return true for it from now on. What could possibly go
wrong? Just two other places need to change, it seems.

fix treatment of signed zeroes in INTERVAL-DIV
Fixes bug reported by Eric Marsden on sbcl-devel: type derivation going wrong
due to one signed zeroes: (/ 0.0 -neg) derives correctly as -0.0, but (/ 0
-neg) derives as 0.0, causing the intersection to be empty causing badness.
Simply remove special casing of division of zero from INTERVAL-DIV:
BOUND-BINOP handles signed zeroes correctly, so no sense complicating the
code by adding handling for them in I-D.

more robust deadlock detection
Lock around building the deadlock chain using WITH-CAS-LOCK after the
tentative deadlock has been detected, and break the deadlock chain before
signaling the error.
This means that a single deadlock is reported only in a single thread.
Fixes occasional failures of deadlock-detection.1 due to a bogus vicious
metacircle. (Two threads detecting the same deadlock, then racing to report
the error detected as another deadlock, the reporting of which in turn looked
like a metacircle to CLOS if PRINT-OBJECT didn't yet have the right method in
cache.)
