ART: Disambiguate access-checks mode from lock-counting
Lock-counting (when structural locking verification failed) is a
special sub-mode of access-checks and must be disambiguated, because
we currently use access-checks mode class-wide when at least one
method soft-fails, but do not stop the compiler/JIT to compile
the "working" methods. So we may end up in the access-checks
interpreter for a working method through deopt without knowing
which locks are already held.

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.

ARM(64): Implement the isInfinite intrinsics
The initial implementation replaced the HInvoke node in the graph
with several other HIRs based on the fact that the difference of
infinities of opposite signs is a NaN value, i.e. the nodes were
equivalent to the expression (x - x != x - x) && (x == x) (which
performs mostly floating-point operations). It was subsequently
abandoned in favor of another HIR implementation using the same
algorithm as the current assembly code (with mostly integer
operations), since it was faster in some simple microbenchmarks
(isInfinite() in a loop).
While the HIR approach had some significant advantages, such as
being architecture-neutral (so all architectures supported by the
compiler benefitted from the changes) and potentially enabling
further optimizations, it also had several limitations, the most
important being that it still needed a HInvoke node, which
defeated its purpose. The reason is that the algorithm requires a
raw conversion to an integer that preserves the bit representation
of the value, which seems not to be expressible in another way -
in particular, HTypeConversion does something entirely different.
Another major problem is that MIPS release 6 has specialized
floating-point classification instructions that are used in the
intrinsic implementation, and which the compiler is unable to use
in the general case (e.g. by recognizing a pattern in the graph),
so the HIR approach resulted in a regression. This could be solved
by doing architecture-specific optimizations earlier, but that
change is beyond the scope of this patch.
There were several other minor issues with the generated code
such as left shifts not being merged into comparisons on ARM64.
More importantly, on ARM Double.isInfinite() resulted in a
sequence of 14 instructions (compared to 6 in the current
implementation) due to the fact that a long is stored in a register
pair, so operations such as left shifts have to be done with two
instructions. This could be worked around by changing the HIR
representation at the cost of increased code complexity.
Given all these issues, the final decision was to implement the
intrinsics using the standard architecture-specific approach.

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.
