The PowerPC CPU has bits in MSR (DR and IR) which control whether addresses are translated. We should respect these instead of mixing physical addresses and translated addresses into the same address space. This is mostly mass-renaming calls to memory accesses APIs from places which expect address translation to use a different version from those which do not expect address translation. This does very little on its own, but it's the first step to a correct BAT implementation.
