8e1c0f5337 CPU table revamp
- Added IBM 486SLC2/40 because somehow I didn't know it existed
- Revoked Dynarec support on the IBM 486 CPUs after several PS/2 machines were buggy with it
- Disallowed Pentium OverDrive and 3.3V 486 CPUs on the AMI 486 clone, Award 486 clone, IBM PS/1 2133, and IBM PS/2 model 70 Type 4 due to discovery that they used either Socket 1 or the original 486 socket
- Disallowed split-rail voltage CPUs (P55C, 6x86L/6x86MX, K6) on all Socket 7 FX and some HX motherboards that don't support it
- Fixed a lot of wrong multipliers on 5th-generation CPUs
- Added mem and cache cycles for the faster K6-2s/K6-3s above 300 MHz
