Helge Deller b1ff64ba4e target/hppa: Copy instruction code into fr1 on FPU assist fault 
The hardware stores the instruction code in the lower bits of the FP
exception register #1 on FP assist traps.
This fixes the FP exception handler on Linux, as the Linux kernel uses
the value to decide on the correct signal which should be pushed into
userspace (see decode_fpu() in Linux kernel).
