History
John Baldwin 4a0f7f1c10 Add initial support for the floating point implementation register. 
- Save the current FIR in the global 'cpuinfo' structure in a new
  'fpu_id' member.
- Decode flags in the FIR when displaying other CPU flags during boot.
- Use the existing "dummy" slot in the floating point register structure
  to export the FIR in process core dumps and via ptrace().  Note that
  while the FIR register is not volatile, this practice of storing the FIR
  in the floating-point register set is used in other OS's.
