1) Apparently wxString::Format is type safe, and passing a u32 to it
with the format "%lu" crashes with a meaningless assertion failure.
Sure, it's the wrong type, but the error sure doesn't help...

2) "A MenuItem ID of Zero does not work under Mac".  Thanks for the
helpful assert message, no thanks for making your construct have random
platform-specific differences for no reason (it's not like menu item IDs
directly correspond to a part of Cocoa's menu API like they do on
Win32).

Incrementing the reference count here isn't necessary, as they construct with a count of 1. Incrementing again results in the attributes not being freed.

This technically also fixes a memory leak in WatchView.cpp, because the table setting was done such that the grid wouldn't take ownership of the table, which means said table wouldn't be deleted in the grid's destructor.

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.
