[PATCH] vect: Add assert to expand_vector_conversion [PR118616]

In some cases (after inliing due to LTO and -O3), GCC cannot figure out that the length of the converts vect is not empty when supportable_indirect_convert_operation returns true. So we get an extra warning because we loop through all but the last entry and GCC decided that `converts.length () - 1`
