Bootstrap failure in tree-vectorizer.c with checking disabled

[Richard Earnshaw]

Dorit, Olga

Your recent patch has broken a non-checking bootstrap:

/home/rearnsha/gnusrc/egcs/gcc/tree-vectorizer.c: In function 
'vect_transform_loop':
/home/rearnsha/gnusrc/egcs/gcc/tree-vectorizer.c:3244: error: 
'vectorization_factor' undeclared (first use in this function)
/home/rearnsha/gnusrc/egcs/gcc/tree-vectorizer.c:3244: error: (Each 
undeclared identifier is reported only once

The declaration of vectorization_factor is wrapped in "#ifdef 
ENABLE_CHECKING", but the use is not.
