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).
