refactor(codegen): remove dead parameters, fields and branches

Drop the never-read StackObject::IsCopy flag and registerStackObject
parameter, the unused NewExprAST forward declaration, the unused Ret
parameter of FunctionGen::emitReturn and CG parameter of
ArrayHandler::loadElement, unused <cstdio> includes, and the
coerceValueToType early returns already covered by the exact LLVM type
check (builtin kinds always map to double/i64/i1/i8).
