80d3a286d1 check bootThunkTable as well as thunkTable in MyProcessor::getStackTrace 
We need to check to see if we caught the thread somewhere in the thunk
code (i.e. about to call a helper function), in which case the stack
and base pointers are valid and may be used to create an accurate
trace.

1558b85acf second attempt to fix "idle to active" fast path 
If another thread succeeds in entering the "exclusive" state while we
use the fast path to transition the current thread to "active", we
must switch back to "idle" temporarily to allow the exclusive thread a
chance to continue, and then retry the transition to "active" via the
slow path.

Joel Dice
75934c8342 provide fast paths for common thread state transitions 
These paths reduce contention among threads by using atomic operations
and memory barriers instead of mutexes where possible.  This is
especially important for JNI calls, since each such call involves two
state transitions: from "active" to "idle" and back.

f6a52e260b specify CONTEXT::ContextFlags before calling GetThreadContext 
Previously, we assumed that the "context" parameter to
GetThreadContext was only an output parameter, but it actually uses at
the value of CONTEXT::ContextFlags on entry to decide what parts of
the structure to fill in.  We were getting lucking most of the time,
because whatever garbage was on the stack at that location had the
necessary bits set.  When we weren't so lucky, we got all zeros for
the register values which sometimes lead to a crash depending on the
state of the thread being examined.

well, in which case we'll need to add a binaryToPE utility.

3787985b25 implement basic finalization support 
This implementation does not conform to the Java standard in that
finalize methods are called from whichever thread happens to be garbage
collecting, and that thread may hold locks, whereas the standard
guarantees that finalize will be run from a thread which holds no locks.
Also, an object will never be finalized more than once, even if its
finalize method "rescues" (i.e. makes reachable) the object such that it
might become unreachable a second time and thus a candidate for
finalization once more.  It's not clear to me from the standard if this
is OK or not.

Nonwithstanding the above, this implementation is useful for "normal"
finalize methods which simply release resources associated with an
object.

47ab980550 fix thread heap overflow corner case in allocate3 
The previous code relied on the invalid assumption that the thread-local
heaps for all threads would have been cleared immediately following a
garbage collection.  However, the last thing the garbage collection
function does is run finalizers which may allocate new objects.  This
can lead allocate3 to call allocateSmall with a size which is too large
to accomodate, overflowing the heap.

The solution is to iterate until there really is enough room for the
original allocation request.

dba72409aa move use of SingleRead::successor; fix build errors 
We now use SingleRead::successor in pickTarget, where we use it to
determine the prefered target site for the successor without requiring
the target to conform to that preference.  The previous code made the
preference a hard requirement, which is not desirable or even possible
in general.

35d1c6e068 add SingleRead::successor; fix build errors 
The SingleRead::successor field is used (when non-null) to further
constrain the SiteMask in SingleRead::intersect based on reads of
successor values (as in the cases of moves and condensed-addressing
combine and translate instructions).

fea92ed995 more work on tail recursion 
We now create a unique thunk for each vtable position so as to avoid
relying on using the return address to determine what method is to be
compiled and invoked, since we will not have the correct return address
in the case of a tail call.  This required refactoring how executable
memory is allocated in order to keep AOT compilation working.  Also, we
must always use the same register to hold the class pointer when
compiling virtual calls, and ensure that the pointer stays there until
the call instruction is executed so we know where to find it in the
thunk.

6e6035505c zero heap space ahead of time when allocating raw storage and garbage collecting, not when allocating individual objects 
This helps us support the Java Memory Model without adding a memory
barrier to every object allocation.  It's also potentially more
efficient, since we zero out each heap segment all at once instead of
bit-by-bit with each object allocation.
