The integer and number variants of these opcodes could need JIT support.

Thanks,

These two patches add jit support for is<compare> style ops (isgt, isge, isle,
islt, iseq, isne) on integers for the sun/sparc platform.

The jitted code follows this "pattern":

           cmp     %r2, %r3
           b<c>,a  next
           mov     1, %r1
           mov     0, %r1
    next:  ..

<c> defining the branch condition.
Thanks,
Stéphane

Sorry the previous core.jit patch for sun contained a typo. The correct
patch file is attached here again.
Thanks!
