e864cabdc0 PowerPC bugfixes:
- 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.

36f696517b As icbi is not a priviledge instruction and is treated as a load by the MMU
it needs to be implemented for every MMU translation mode.

d9bce9d99f Make it safe to use 64 bits GPR and/or 64 bits host registers.
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.

76a66253e5 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.

111bfab3b5 This patch adds little-endian mode support to PPC emulation.
This is needed by OS/2 and Windows NT and some programs like VirtualPC.
This patch has been tested using OS/2 bootloader (thanks to Tero
Kaarlela).
