[tree-ssa] Correct the initialization of an edge flag

[Pop Sébastian]

Hi,

This patch marks the following edges as fallthru:

               LOOP_EXPR
	           |
                   v
             LOOP_EXPR_BODY 

Bootstrapped on i686.  Ok?



	* tree-cfg.c (make_loop_expr_edges): Mark edges from loop_expr to 
	their body with EDGE_FALLTHRU.
