Workaround invokesuper underspecified behavior.
The verifier allows invokesuper on a class unrelated
to the referring class. However, the runtime uses the vtable of
the super class of the referring class to lookup the ArtMethod.
Since the receiver has no relation to the referring class, this lead
to either jumping to a wrong method, or "luckily" throw a
NoSuchMethodError if the vtable index is out of bounds of the super
class of the referring class.
This changes the runtime behavior to always throw NoSuchMethodError
when hitting such invokesuper.
Also, we make the verifier consistent with the runtime by treating
such calls unresolved.

Correct monitor pool synchronization
The previous implementation allowed a thread looking up a monitor
to see an uninitialized monitor_chunks_ list if the list had
just been resized. The obvious small fix would be to replace the
relaxed load in LookupMonitor with an acquire load. But the
extra fence (on ARM) may involve an appreciable performance hit.
This instead redesigns the data structure to avoid the race in
LookupMonitor, along with the need to use atomics there at all. The
down side is a little more address arithmetic in LookupMonitor(),
a mild decrease in the limit on the total number of monitors, and
use of one extra page, since we now always reserve space for the
first page worth of monitor chunk pointers.
To me, the new algorithm feels cleaner and easier to reason about.
Although this problem was externally reported, it seems unlikely
that it was responsible for frequent failures. It could only
be triggered when the monitor chunk list was resized, which should
be quite rare.

Reduce memory lost by ArenaAllocator for large allocations.
When allocating from a new arena, check if the old arena has
more remaining space than the new one after the current
allocation. If so, keep using the old arena to reduce the
amount of "lost" arena memory. This can happen when we try
to allocate more than half the default arena size. If the
allocation exceeds the default arena size, it's very likely
to happen even though the ArenaPool could still provide some
much larger previously allocated arena.
Also avoid artithmetic overflow when checking if the
request can be satisfied from the current arena.
And abort immediately if calloc() fails.
