Silence a clang warning in tree-vect-slp.cc about an unused variable

Since r15-4695-gd17e672ce82e69 (Richard Biener: Assert finished
vectorizer pattern COND_EXPR transition), the static const array
cond_expr_maps is unused and when GCC is compiled with clang, it warns
about that.

This patch simply removes the variable.
