Simplify heap bitmap allocation.
Rather than use ashmem and mmap directly, we now call out to a common
abstraction which does both. A name is now required. This should go
unnoticed as all callers provided a name anyway.

When aliasing a bitmap, use smallest available limit.

conservative max value of the heap limit. This is perfect for the
zygote but is oversized for application heaps that are not anywhere
near full. Now the code consults the live bitmap and will use its max
value if it is smaller than the heap limit.

Use the new pendingNext field to thread pending references.
Presently, the garbage collector uses the queueNext field to thread
references discovered during a trace. This is unsafe as a user may
simultaniously call enqueue on a discovered reference which will alias
the queue of pending references to the queue of a reference queue.
To avoid this problem, the garbage collector uses the pendingNext
field to thread together pending references. If, during reference
processing, the garbage collector discovers that an object has been
enqueued by the user, it will short circuit referencing processing for
that object.
As part of this change, the the reference object processing routines
have been reorganized to eliminate the macrology used by the pending
reference queueing. In addition, the pending reference lists are now
circular to ensure pendingNext of a pending reference is never NULL.

Emit volatile field access instructions.
Easier said than done. The trick is that we need to ensure that the
instruction replacement happens even if the verifier and optimizer
are not enabled in dexopt.
We're currently doing the -wide-volatile replacement during
verification, but that's not so great, since we collapse things like
iget-byte and iget-char into a single iget-volatile, losing the field
width. We could recover it from the field declaration, but doing it
during verification is really just sort of wrong to begin with.
The substitution isn't technically an "optimization", but it's easiest
to do it during the opt pass, and we already have a convenient "is
optimized" flag that helps ensure that we do the replacement pass
exactly once.
Optimizing at run time means making a private copy of shared pages,
because the pages are mapped shared/read-only out of the DEX file.
We could use up a lot of physical memory if we applied all possible
optimizations, so we need a notion of "essential" and "non-essential"
optimizations. If we're not running in dexopt, we only do the
essential ones, which should leave most methods untouched.
Replacement of 32-bit instructions is only strictly necessary when
we're building for SMP. On a uniprocessor, the 32-bit operations
are inherently atomic, and memory barriers aren't required. However,
the JIT may benefit from having volatile accesses identified by opcode.
Since the current branch doesn't support any SMP products, I'm enabling
the instruction generation for all platforms so that we can give it
some exercise.
While making this change I noticed that the exclusion mechanism for
breakpoints and optimization/verification was only serving to avoid
a data race (e.g. breakpoint being overwritten by an instruction
rewrite). It wasn't guaranteed to prevent races when two threads
toggled pages between read-write and read-only while making an update,
since a 4K page can hold code for more than one class. This has been
corrected by adding a mutex.
This change:
- Introduces the notion of essential vs. non-essential optimizations.
- Adds generation of 32-bit *-volatile instructions for all platforms.
- Moves generation of *-wide-volatile from the verifier to the optimizer.
- Allows the optimizer to modify code at run time.
- Tweaks optimizeMethod() for "best effort" rather than "fail early".
- Adds a DEX-granularity mutex to the bytecode update functions.
This also begins the removal of PROFILE_FIELD_ACCESS, which hasn't been
used for much and is mostly just in the way.

Change how a null threadgroup is displayed.
We used to show "(BOGUS GROUP)", but that's not quite accurate since
the group is actually NULL. Since there are now circumstances in
which you see this, and they'll likely be associated with Thread
initialization, it's more accurate and useful to say
"(null; initializing?)" instead.

Add a mode for concurrently marking and sweeping.
When enabled, the mutator threads will be resumed while tracing
proceeds from the roots. After the trace completes the mutator
threads are suspended, the roots are remarked, and marked objects
are scanned for updates and re-marked.
There are two limitations to this implementation. For the sake
of expediency, mutators are not permitted to allocate during the
concurrent marking phase. This will be addressed in a subsequent
change. As there is no write barrier, all objects, rather than
just those objects assigned to during the concurrent phase, are
scanned for updates. This will be addressed after a write barrier
is implemented.

The change affects diagnostic output but doesn't change anything about
dex file production, per se. I also added a new test each for dx and
the vm, checking that the warning gets emitted and demonstrating the
effect (respectively).
Though it's a pretty minor change, I bumped up the version number of dx.
Added bonus: Wrapped a couple of too-long lines that I happened to notice.
