art::Mutex and art::ConditionVariable were DCHECKing that the value was
zero on entering the constructor without ever initializing the value.
Since 0 is a sensible default, make it the default for art::Atomic

Reduce stack usage for overflow checks

This reduces the stack space reserved for overflow checks to 12K, split
into an 8K gap and a 4K protected region.  GC needs over 8K when running
in a stack overflow situation.

Also prevents signal runaway by detecting a signal inside code that
resulted from a signal handler invokation.  And adds a max signal count to
the SignalTest to prevent it running forever.

Also reduces the number of iterations for the InterfaceTest as this was
taking (almost) forever with the --trace option on run-test.

been destroyed yet (which is verified with a check). This only happens when the
