[SPARC] Emit compareAndSwap for AtomicInteger and AtomicLong, Removing o7 register from usable ones, as this register is always overwritten, when using Call or JumpAndLink instructions in SPARC, even callee does not overwrite explicitly, implicit exception is defined when doing integer division, parameter constraint narrowed to only register on Unary2Op, Fix SPARCTestOp, as it did a compare instead of an and with condition codes
