sablevm for AIX

It has been quite a struggle but finally I have been able to run 
sablevm on AIX.

I've just submitted patches for sablevm and one for classpath, and will 
soon write some notes on how to do the build. And, yes, I know that I'm 
still owing notes for the Mac OS X build process :)

One of the main problem issues is the AIX assembler (you can't use gnu 
as on AIX) which meant that I built this as switched rather than 
inline. AIX as doesn't support gnu-assembler-style "local labels" and I 
haven't yet thought of a reasonable way to get the same effect. If 
anyone has some ideas I'd be happy to hear them.

p.s. my test includes jni, but not gtk/awt/swing etc as our usage 
doesn't include those
