d254f41817 Banshee/Voodoo 3 status returns busy when FIFO thread is busy, regardless 
of command/cmdfifo/render thread status. Fixes some 2D races where drivers
start to write to framebuffer while (final) 2D blit command is still
running.

114cdd7a15 Add VIA Cyrix III CPUs. Note that this is currently limited to 500 MHz, 
as Windows 98 won't boot on anything any faster than this. This is most
likely a limitation of the current timer subsystem.

f6406c77e5 Add fast path in Banshee overlay render; if overlay is unfiltered and 
unscaled then just write straight to destination buffer.

2cf57ab8b2 If Banshee video overlay is full screen (as would be the case for 
full screen 3D), don't bother rendering the desktop behind it.

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

0d7103368a Add register rename optimisation to dynarec to eliminate some redundant 
UOP_MOVs.

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.
