Flyinghead 74aae115ee sh4: implement C and WT MMU bits in cache. Use mem handlers everywhere
o/icache use C and WT bits from mmu to override cache and copy back
settings (fixes Windows CE)
move mem handlers setup out of mmu into sh4_mem. Call in dc_resume and
detect transitions interp -> dynarec to flush caches.

Flyinghead e3d95f2258 wince: unify _vmem and vmem32. Use 4GB virtual space on 64-bit arch
On 64-bit architectures, _vmem first tries to allocate 4GB then falls
back to 512 MB.
The same virtual space is now used by _vmem and vmem32 (mmu)

Stefanos Kornilios Mitsis Poiitidis 4a060b5635 sh4/mmu: C++ exception based sh4 exception support. Won't run wince yet.
- Rewrite mem ops to only modify regs after exception path
- Throw & catch logic for interpreter that raises the exception
- Re-enabled some commented mmu code

Stefanos Kornilios Mitsis Poiitidis dcd77326cc sh4/mmu: Import the old mmu implementation from nullDC.
Reicast doesn't support exceptions yet, so this isn't of much use now,
and is intended mostly as documentation. nullDC used some call stack
hooking magic to handle exceptions, which was never generic and clean
enough to be worth the effort to port to Reicast.
