isl_ast_codegen.c: after_each_for: fix memory management annotation

The wrong annotation has been used ever since this function was introduced
in 10e0bab (add before_each_for/after_each_for callbacks,
Tue Nov 20 20:22:35 2012 +0100).

isl_ast_codegen.c: remove remnants of code removed before inclusion

The AST generation code has undergone many changes before it was
included in the master branch in 5888ac1 (add support for generating ASTs
from schedule relations, Mon Sep 17 22:11:06 2012 +0200).
Some references to old code got left in by mistake.
We already removed similar comments from isl_ast_build_expr.c
in 19609c1 (isl_ast_build_expr.c: remove remnants of code removed
before inclusion, Sat Sep 29 11:11:19 2012 +0200).
