Improve handling of daemon threads after runtime shutdown
The main issue comes from the fact that user daemon threads are
allowed to continue running after the runtime has shutdown. They may
still have a JNI env pointer. To prevent crashing if they call into
the env, we replace the function pointers with functions that sleep
forever.
The other issue is that user daemon threads that are blocked in an
ART condition variable may get woken up by another user daemon inside
of Monitor::Notify or by a spurious wakeup (i.e. SIGQUIT). To deal
with this issue, we check the JNI env for shutdown runtime when we
are woken up from a condition variable wait. This check fixes test
132 with --host --gdb --interpreter. Previously this test crashed
since dlclose was somehow causing a spurious futex wakeup.
TODO: Investigate adding a unit test.

ART: Make trampoline compiler pointer-size-safe
The trampoline compiler uses offsets of runtime structures which
may change with the pointer size.
Add offset tests to jni_internal_test.

ART: Add CheckJNI lock checking
JNI MonitorEnter and MonitorExit have similar rules to structured
locking. Count locks in CheckJNI mode.

Move to newer clang annotations
Also enable -Wthread-safety-negative.
Changes:
Switch to capabilities and negative capabilities.
Future work:
Use capabilities to implement uninterruptible annotations to work
with AssertNoThreadSuspension.

ART: IRT refactor
IRT creation might fail. Add a path that allows to bypass the aborts
and instead signal validity. Hide this path with a private constructor,
rewrite users to use a static Create method.
