V.E.L.O.C.I.T.Y.-OS JIT Compiler Adds Classic Optimization Passes

The V.E.L.O.C.I.T.Y.-OS project implements four classic compiler optimization passes in its JIT compiler, including constant folding and dead code elimination. These passes run on the AST before emitting x86-64 machine code to reduce redundancy. The work is part of a 12-part series building a bare-metal OS that runs entirely in L3 cache.
