More changes to the IOP's memory model. Some of these are experimental and might cause problems (needs testing). Quick rundown:

* The R3000 does not have a TLB, and has no valid addresses mapped above page 0x2000 in physical memory [lower 512M].  Thus all addresses can have the top 6 bits masked off and still retain full validity.  For example, address 0xbfc0 is simply a mirror of physical address 0x1fc0.  Technically speaking, a full emulation of the IOP memory model would raise bus error exceptions for accesses between 0x2000 to 0x8000 segments (instead of treating them as mirrors of the lower 0x2000 segment), but buss errors are generally fatal (unrecoverable) program errors that would never happen within the context of game emulation.

* The IOP's SIF register space is only 256 bytes, and then mirrored repeatedly through it's 64k page at 0x1d00.
