Great PowerPC emulation code resynchronisation and improvments:

- Add status file to make regression tracking easier
- Move all micro-operations helpers definitions into a separate header:
  should never be seen outside of op.c
- Update copyrights
- Add new / missing PowerPC CPU definitions
- Add definitions for PowerPC BookE
- Add support for PowerPC 6xx/7xx software driven TLBs
  Allow use of PowerPC 603 as an example
- Add preliminary code for POWER, POWER2, PowerPC 403, 405, 440, 601, 602
  and BookE support
- Avoid compiling priviledged only resources support for user-mode emulation
- Remove unused helpers / micro-ops / dead code
- Add instructions usage statistics dump: useful to figure which instructions
  need strong optimizations.
- Micro-operation fixes:
  * add missing RETURN in some micro-ops
  * fix prototypes
  * use softfloat routines for all floating-point operations
  * fix tlbie instruction
  * move some huge micro-operations into helpers
- emulation fixes:
  * fix inverted opcodes for fcmpo / fcmpu
  * condition register update is always to be done after the whole
    instruction has completed
  * add missing NIP updates when calling helpers that may generate an
    exception
- optimizations and improvments:
  * optimize very often used instructions (li, mr, rlwixx...)
  * remove specific micro-ops for rarely used instructions
  * add routines for addresses computations to avoid bugs due to multiple
    different implementations
  * fix TB linking: do not reset T0 at the end of every TB.
