andsi3_internal7 and andsi3_internal8 generate invalid LT and GT condition
codes. This is because these bits of the condition register are set from
all 64 bits of the register in 64-bit mode. I don't believe it is possible
to have all of EQ, LT and GT correct using only two rlwinm instructions in
the mask_operand_wrap case.
Causes failure of gcc.c-torture/execute/930718-1.c
