0004 — Emit C++ directly from the checked AST, in one translation unit
Context. CMP-06/08 describe HIR and MIR (SSA) stages; CMP-09 asks for one .cpp/.h pair per module. The first increment
aims at an end-to-end path.
Choice. emit-cpp.ts walks the TypeScript AST with the types computed by sema.ts and writes a single zinc_main.cpp:
string literal pool, forward declarations, classes in inheritance order, globals, prototypes, bodies, one __init/__deinit
per module (C++ namespace m_<path>), then main. Generics become C++ templates.
Consequences. No optimisation passes of our own (the C++ compiler does the work), no --emit=hir|mir, and whole-program
compilation comes for free (CMP-12 is approximated by -ffunction-sections + dead-strip). HIR/MIR will be introduced between
Sema and the emitters without changing the runtime.
