3d7b417e13 target-ppc: Convert XER accesses to TCG
Define XER bits as a single register and access them individually to
avoid defining 5 32-bit registers (TCG doesn't permit to map 8-bit
registers).

bd7d9a6d7b ppc: cleanup register types
- use target_ulong for gpr and dyngen registers
- remove ppc_gpr_t type
- define 64-bit dyngen registers for GPE register on 32-bit targets

a4f30719a8 PowerPC hypervisor mode is not fundamentally available only for PowerPC 64.
Remove TARGET_PPC64 dependency and add code provision to be able
  to define a fake 32 bits CPU with hypervisor feature support.

b172c56a6d Always make all PowerPC exception definitions visible.
Always make the hypervisor timers available.
Remove all TARGET_PPC64H checks, keeping a few if (0) tests for cases
that cannot be properly handled with the current PowerPC CPU definition.

056401eae6 PowerPC 601 need specific callbacks for its BATs setup.
Implement PowerPC 601 HID0 register, needed for little-endian mode support.
As a consequence, we need to merge hflags coming from MSR with other ones.
Use little-endian mode from hflags instead of MSR during code translation.

2f462816ac Implement power-management for all defined PowerPC CPUs.
Fix PowerPC 970MP definition.

0411a97258 Gprof prooved the PowerPC emulation spent too much time in MSR load and store
routines. Coming back to a raw MSR storage model then speed-up the emulation.
Improve fast MSR updates (wrtee wrteei and mtriee cases).
Share rfi family instructions helpers code to avoid bug in duplicated code.
Allow entering halt mode as the result of a rfi instruction.
Add a new helper_regs.h file to avoid duplication of special registers
 manipulation routines (currently XER and MSR).
