codegen: check for PPC64 ISEL in condmove tests
ISEL is roughly equivalent to CMOV on PPC64. Verify ISEL generation
in all reasonable cases.
Note "ISEL test x y z" is the same as "ISEL !test y x z". test is
always one of LT (0), GT (1), EQ (2), SO (3). Sometimes x and y are
swapped if GE/LE/NE is desired.
