Fix PowerPC 32 emulation on 64 bits hosts:
...
we can use 64 bits registers but not pretend page is 1kB long
As it seems most Linux programs assume page-size is 4kB, never allow
1kB pages for user-mode only emulation.

New model for PowerPC CPU hardware interrupt events:
...
move all PowerPC specific code into target-ppc/helper.c to avoid polluting
the common code in cpu-exec.c. This makes implementation of new features
(ie embedded PowerPC timers, critical interrupts, ...) easier.
This also avoid hardcoding the IRQ callback in the OpenPIC controller,
making it more easily reusable and allowing cascading.

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.
