fix jsr/ret code generation bug
...
We were generating code to marshal values into place prior to a jump,
but placing it after the jump instruction, which made it useless.

specify java.home system property in GNU Classpath build
...
Currently, we just set this to /tmp (or the equivalent) since Avian
doesn't really have a home. This avoids a NullPointerException from
javax/xml/parsers/SAXParserFactory.

replace calls to ExceptionOccurred with calls to ExceptionCheck
...
The latter is cheaper (avoids a state transition and possible memory
allocation) when we just want to know if an exception is thrown
without needing a handle to that exception.

reuse JNI references when possible
...
Before allocating a new reference in NewGlobalReference or when
creating a local reference, we look for a previously-allocated
reference pointing to the same object. This is a linear search, but
usually the number of elements in the reference list is small, whereas
the memory, locking, and allocation overhead of creating duplicate
references can be large.

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.

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.
