The movdi, movdf and movxf patterns allow both operands to be offsettable

visible in the failure of gcc.c-torture/execute/pr97073.c when compiled
with LTO (where cprop optimizes out the AND operation; the failure also
occurs without LTO when the AND is removed). Split the constraints so
that the operands cannot both be "o" in the same insn.

Thanks for taking care of this stuff!
