Add VECTOR_BITS to tree-vect.h

Several vector tests are sensitive to the vector size.  This patch adds
a VECTOR_BITS macro to tree-vect.h to select the expected vector size
and uses it to influence iteration counts and array sizes.  The tests
keep the original values if the vector size is small enough.

For now VECTOR_BITS is always 128, but the SVE patches add other values.
