mmel a31f837855 Cleanup structures related to VFP and/or mcontext_t.
- in mcontext_t, rename newer used 'union __vfp' to equaly sized 'mc_spare'.
  Space allocated by 'union __vfp' is too small and cannot hold full
  VFP context.
- move structures defined in fp.h to more appropriate headers.
- remove all unused VFP structures.
