Add a vect_worthwhile_without_simd_p helper routine
The vectoriser sometimes considers lowering "vector" operations into N
scalar word operations. This N needs to be fixed at compile time, so
the condition guarding it needs to change when variable-lengh vectors
are added. This patch puts the condition into a helper routine so that
there's only one place to update.
