Pentium CPUID detection test case

[joncampbell123]

Here's a demo that seems to have CPUID awareness for Pentium processors.

It shows detection logic apparently for:

• MMX extensions
• Pentium Overdrive processors
• Pentium processors capable of dual-CPU configurations
• APIC interrupt controllers
• A "3D Blaster PCI" sound card (whatever that is)

Perhaps DOSBox-X could add a pentium_overdrive cpu type?

Also might be a good stress case for the pentium_mmx cpu type.

Later when DOSBox-X gets an APIC interrupt controller, might also test to see what happens.

Not sure how DOSBox-X would emulate dual-CPU Pentium, or even what the hardware is like.
