Laurent Vivier 50aa85e560 target/m68k: implement opcode fetoxm1
Example provided in the launchpad bug fails with:

qemu: uncaught target signal 4 (Illegal instruction) - core dumped
Illegal instruction (core dumped)

It appears fetoxm1 is not implemented:

IN: expm1f
0x800005cc: fetoxm1x %fp2,%fp0
Disassembler disagrees with translator over instruction decoding
Please report this to qemu-devel@nongnu.org

(gdb) x/2hx 0x800005cc
0x800005cc: 0xf200 0x0808

This patch adds the instruction.
