But I, too, think it should be general (if at all), not target specific. We could seed it from largest integer/float vector-mode that has an add optab for example if the target does not override it. Note the distinction between FP and int makes it a bit awkward if you think about AVX vs. AVX2 for example. But then so is -mpreferred-vector-with in that case. FEs need to expose extra "generic" macros, so adjusting component accordingly.
