- Add the other CPU_* codes (got them from a PDB)

- Add the other CPU_* codes (got them from a PDB)
- Restructure the CPU vendor check in KiGetFeatureBits with a switch statement
- Enable experimental support for Cyrix, Transmeta, Centaur and Rise CPUs (experimental = mostly untested)
- Just add CMPXCHG8B support to the feature bits for Centaur CPUs like it's already done for Rise CPUs without touching any MSRs.
  The instruction already works properly by default according to two official Centaur datasheets. Also Geoz on IRC already reported that his C3 Nehemiah works with ReactOS after this patch.
- Enable the 3DNow detection code through extended CPUID also for Centaur CPUs (all CPUs from IDT WinChip C6 to VIA C3 Ezra-T supported it)
- Report the presence of AMD K6 MTRRs also for mobile AMD K6-2+/K6-III+ CPUs (model D)
