[PATCH 1/6] insn-selector: add dummy rules for floating-point

[Vegard Nossum]

Thanks a LOT to Arhur Huillet for adding these dummy rules. This
prevents jato from crashing when we try to jit-compile floating-point
bytecodes.

PS: You might want to put these rules in different locations. I don't
know the proper monoburg style.
