refactor(codegen): split large emitStmtImpl arms into methods

Move the self-contained FunctionDef, INPUT, OUTPUT and READFILE branches
of emitStmtImpl into private emitFunctionDefStmt, emitInputStmt,
emitOutputStmt and emitReadFileStmt methods. The dispatch order and the
branch bodies are unchanged.
