but on the execution mode that will be effective after the return.
Add rfci, rfdi and rfmci for BookE PowerPC.
Extend mfdcr / mtdcr and implement mfdrcx / mtdcrx.

- must clear carry bit when doing addic with a zero immediate value
- fix missing RETURN in micro-operation that would lead to random failures
and crashes
- add USE_PRECISE_EMULATION compilation-time option to choose between
getting exact floating point results and fast but less accurate computation.

it needs to be implemented for every MMU translation mode.

For "symetry", add 64 bits versions of all modified functions.
As a side effect, add a lot of code provision for PowerPC 64 support.
Move overflow and carry checks in common routines for simple cases.
Add isel and popcntb instructions from PowerPC 2.03 specification.
Remove remaining micro-operations helpers prototypes from op.c.
Fix XER_BC field to be 7 bits long.
Add power management support for PowerPC 603 & 604.
Fix compilation warnings.

- 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.
