The attached testcase is miscompiled on powerpc and powerpc64, 3.3 branch only.
It can be seen in the 09.cse dump.
g++ -O2 -c doubleif.ii -da
check the doubleif.ii.09.cse dump, it will contain a single
reg:CC 123 user in a conditional jump without setter.
the testcase compiles correctly on mainline.
