Add support for fnop instruction on x86 and amd64

This implements FNOP in guest_amd64_toIR.c and guest_x86_toIR.c by
simply skipping the instruction. Which is OK for now since one of the
x87 FP Limitations is no FP exceptions, except for handling stack
over/underflow.

Add fnop to none/tests/{amd64,x86}/insn_fpu.{def,stdout.exp}.

Also update old 3_1_BUGSTATUS.txt to correct bug number.
