Add new sane low-level memory accessors for PowerPC that do proper
size or zero extension, with homogenous names.
Fix load & store strings: those are now endian-sensitive, by definition.
Fix dcbz: must always align the target address to a cache line boundary....

Remove shared macro used to define PowerPC implementations instructions sets:
tend more to propagate bugged definition than simplify the code.
Check and fix PowerPC 6xx implementations definitions.
Misc fixes in PowerPC CPU list.

A little more granularity in PowerPC instructions definition is needed
in order to implement Freescale cores.

PowerPC 601 need specific callbacks for its BATs setup.
Implement PowerPC 601 HID0 register, needed for little-endian mode support.
