Basic implementation of an "array" ( We use native memory ) of function pointers, pointing to generic instantiations!

All 64 moves get their own specialized method body, with irrelevant code eliminated

Method selection code looks something like...

L00000:  mov rax, 0x2a362746c50
L00010:  mov rax, [rax+rdx*8]
L00014:  jmp rax
Optimization Tier - OptimizedTier1

No need to do this. It's already done by Util.cs.

Does that even work? The ModuleInitializer attribute seems to be missing. Either way, RIP startup perf

I believe it works? — Not 100% sure, but running it seems to be fine.

The start-up performance isn't actually hurt that much.
