Preliminary VIA Cyrix III emulation

This adds preliminary emulation of the first-gen Samuel core, used in the VIA Cyrix III CPU, at clock speeds from 66 to 700 MHz. This also moves the 440BX emulation out of the dev-branch.

Things working:
- CPUID
- Windows 98SE
- Timings seem identical between WinChip/W2's integer section and this

Things left to do:
- 3DNow on old dynarec
- Half-speed FPU (currently simulated with WinChip 1 timings instead of WinChip 2)
