Understand Dynamic Recompilation (Dynarec) for Emulation Speedup

Document dynamic recompilation concepts in C.

Requirements:

• Define structs for GuestInstruction, TranslatedBlock, and CodeCache
• Implement a function that prints a sample guest instruction and its hypothetical host translation
• Implement a basic block detector that scans a guest instruction array and prints block boundaries
• Implement a code cache that stores translated blocks keyed by guest PC address
• Print how block chaining works: show a guest block ending in a jump and how it links to the next block
• Document code cache invalidation: print when and why blocks are removed from the cache
• Include a comparison table showing interpreter overhead vs dynarec overhead per instruction
• Print a summary of the translation pipeline: fetch guest block, emit host code, store in cache, execute
