David Daney 515b029d00 MIPS: Send proper signal and siginfo on FP emulator faults. 
We were unconditionally sending SIGBUS with an empty siginfo on FP
emulator faults.  This differs from what happens when real floating
point hardware would get a fault.

For most faults we need to send SIGSEGV with the faulting address
filled in in the struct siginfo.
