1d9489a76e fix a couple of 64-bit-op-on-32-bit-system bugs 
We weren't properly handling the case where a 64-bit value is
multipled with itself in multiplyRR, leading to wrong code.  Also,
addCarryCR didn't know how to handle constants more than 8-bits wide.

4f23601b56 fix corner cases which led to crashes in JIT compiler 
Compiling the entire OpenJDK class library into a bootimage revealed
some corner cases which broke the compiler, including synchronization
in a finally block and gotos targeting the first instruction of an
unsynchronized method.

19dbc61e9f for heapdump=true builds, optionally generate dump on OOM 
If the VM runs out of heap space and the "avian.heap.dump" system
property was specified at startup, the VM will write a heap dump to
the filename indicated by that property.  This dump may be analyzed
using e.g. DumpStats.java.

64601e6f3e name VM-internal classes for heapdump=true builds 
This makes heap dumps more useful since these classes are now refered
to by name instead of number.

This commit also adds a couple of utilities for parsing heap dumps:
PrintDump and DumpStats.

d0a6096eb0 add support for accessing embedded JARs as if they were directories 
This allows OpenJDK to access time zone data which is normally found
under java.home, but which we must embed in the executable itself to
create a self-contained build.  The VM intercepts various file
operations, looking for paths which start with a prefix specified by
the avian.embed.prefix property and redirecting those operations to an
embedded JAR.

For example, if avian.embed.prefix is "/avian-embedded", and code
calls File.exists() with a path of
"/avian-embedded/javahomeJar/foo.txt", the VM looks for a function
named javahomeJar via dlsym, calls the function to find the memory
region containing the embeded JAR, and finally consults the JAR to see
if the file "foo.txt" exists.

d0d53e2e10 fix custom-classloader-related concurrency problems and other bugs 
The main changes in this commit ensure that we don't hold the global
class lock when doing class resolution using application-defined
classloaders.  Such classloaders may do their own locking (in fact,
it's almost certain), making deadlock likely when mixed with VM-level
locking in various orders.

Other changes include a fix to avoid overflow when waiting for
extremely long intervals and a GC root stack mapping bug.

cddea7187d preliminary support for using OpenJDK's class library 
Whereas the GNU Classpath port used the strategy of patching Classpath
with core classes from Avian so as to minimize changes to the VM, this
port uses the opposite strategy: abstract and isolate
classpath-specific features in the VM similar to how we abstract away
platform-specific features in system.h.  This allows us to use an
unmodified copy of OpenJDK's class library, including its core classes
and augmented by a few VM-specific classes in the "avian" package.

250a77dc13 handle empty strings properly in Pattern.split 
We were incorrectly returning an empty array when the input was empty,
whereas we ought to return an array containing a single empty string.
When the pattern to match was empty, we went into a loop to create an
infinite list of empty strings, only to crash once we've run out of
memory.  This commit addresses both problems.

The shiftLeftC function in powerpc.cpp was miscompiling such shifts,
leading to crashes due to illegal instructions and other weirdness due
to instructions that meant something completely different.  This
commit fixes that and adds a test to Longs.java to make sure it stays
fixed.

99bb7924b0 fix stack frame mapping code for exception handlers 
Previously, the stack frame mapping code (responsible for statically
calculating the map of GC roots for a method's stack frame during JIT
compilation) would assume that the map of GC roots on entry to an
exception handler is the same as on entry to the "try" block which the
handler is attached to.  Technically, this is true, but the algorithm
we use does not consider whether a local variable is still "live"
(i.e. will be read later) when calculating the map - only whether we
can expect to find a reference there via normal (non-exceptional)
control flow.  This can backfire if, within a "try" block, the stack
location which held an object reference on entry to the block gets
overwritten with a non-reference (i.e. a primitive).  If an exception
is later thrown from such a block, we might end up trying to treat
that non-reference as a reference during GC, which will crash the VM.

The ideal way to fix this is to calculate the true interval for which
each value is live and use that to produce the stack frame maps.  This
would provide the added benefit of ensuring that the garbage collector
does not visit references which, although still present on the stack,
will not be used again.

However, this commit uses the less invasive strategy of ANDing
together the root maps at each GC point within a "try" block and using
the result as the map on entry to the corresponding exception
handler(s).  This should give us safe, if not optimal, results.  Later
on, we can refine it as described above.

45476eb591 fix handling of volatile longs and doubles on PowerPC 
We were miscompiling methods which contained getfield, getstatic,
putfield, or putstatic instructions for volatile 64-bit primitives on
32-bit PowerPC due to not noticing that values in registers are clobbered
across function calls.

The solution is to create a separate Compiler::Operand instance for each
object monitor reference before and after the function call to avoid
confusing the compiler.  To avoid duplicate entries in the constant pool,
we add code look for and, if found, reuse any existing entry for the same
constant.

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.

9fe00836f7 fix stack mapping code to do as many passes as necessary 
Previously, we had been doing exactly two passes over the event log to
caculate the stack object reference map at each trace point.  It turns
out the correct number of passes depends on how many incorrect
assumptions we make about what the stack looks like at instructions with
multiple predecessors (i.e. targets of jumps and branches).

Each time we detect we've made one or more incorrect assumptions during
a pass, we must do another pass to correct those assumptions.  That pass
may in turn reveal further incorrect assumptions, and so on.

71e7a6d796 Simple non-blocking client and server example programs. The client 
actually simulates blocking IO by implementing a Socket OutputStream, and
sends a file to a port.  The server listens on a port and dumps the output
to test files.  Together, these classes can be used to send a file from
a client to a server machine over a socket.
