d1565abd68 Fixed bug - added code in pushUnconstrainedIGNodes() to check whether a node 
is already pushed to stack by a previous call to the same method.

b7f06f46a1 Fixed instruction information for RDCCR and WRCCR. 
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).
