25fe224ea9 Add dynarec optimisation for UOP_MOV_IMM, to avoid register allocation 
if the destination register won't be immediately used again.

cccaf86fd3 Mark some exceptions (mainly v86 related) as 'expected', meaning they 
won't cause a code block deletion. This speeds up some v86 code due
to a reduction in code block churning.

1915149391 Increase Banshee revision to 3, matching my real CL Banshee card. Removes 
the need for any fogTable hack, which is in any case inconsistently applied
by drivers and I think may only be needed on pre-production devices.

19a5dfa579 Added Voodoo Banshee emulation. 
Known issues :
- Tiled framebuffer layout is not yet implemented. This causes horizontal
  offsets in some 2D 16bpp stuff (eg FMV in Tomb Raider 2, UI in Expendable)
- Fog is broken and currently disabled for Banshee
- Possibly at least 1 race in 2D blitter emulation
- A few things not yet emulated - overlay filters, some (rarely used) 2D
  blitter functions
