IL to Native compilation

Mostly the precursors to the AOT compiler we see in .Net 7/8:

• IL2CPU - IL2CPU is a compiler for .NET IL code to compile to assembly language for direct booting.
• bflat - A single ahead-of-time crosscompiler and runtime for C# (based upon Microsoft's Roslyn and NativeAOT).

x86 architecture/instruction set

• x86 Registers
• Intel x86 Assembly Language Programming
• x86-bare-metal-examples - Dozens of minimal operating systems to learn x86 system programming.
