6991596: JSR 292 unimplemented adapter_opt_i2i and adapter_opt_l2i on  
SPARC
Reviewed-by:

On SPARC adapter_opt_i2i and adapter_opt_l2i are still unimplemented.
This needs to be filled in.

This change also adds a testcase that tests as much conversions as
currently possible (there are some bugs in the current RI).
