tree-optimization/105394 - vector lowering of compares
The following fixes missing handling of non-integer mode but
masked (SVE or MVE) compares in vector lowering by using the
appropriate mask element width to extract the components and
adjust the index.

* tree-vect-generic.cc (expand_vector_condition): Adjust
comp_width for non-integer mode masks as well.
