aurel32 6c01bf6c7b target-ppc: fix fres, fsqrte and remove useless code 
- fres and fsqrte should not assign a float32 number to a float64 value.
- fre, fres and fsqrte are checking for cases already taken into account
  by softfloat and softfloat native. Remove those useless tests.

aurel32 76db3ba44e target-ppc: memory load/store rework 
Rework the memory load/store:
- Unify load/store functions for 32-bit and 64-bit CPU
- Don't swap values twice for bit-reverse load/store functions
  in little endian mode.
- On a 64-bit CPU in 32-bit mode, do the address truncation for
  address computation instead of every load store. Truncate the
  address when incrementing the address (if needed)
- Cache writes to access_types.
- Add a few missing calls to gen_set_access_type()
