/*
 * Implementor's notes: seanptmaher
 *
 * this intrinsic has many (7 pages worth) of variations on it, so
 * this file might become a dumping ground for various
 * implementations. I'm only going to write the `cvt` intrinsics for
 * now, but off the top of my head, we've got:
 *
 * - vcvt* <- round towards 0
 * - vcvtn* <- round to nearest with ties to even
 * - vcvtm* <- round towards minus infinity
 * - vcvtp* <- round towards plus infinity
 * - vcvta* <- round to nearest with ties to away
 *
 * and there are a bunch of variations on these. More information can
 * be found here:
 * https://developer.arm.com/architectures/instruction-sets/simd-isas/neon/intrinsics?page=1&search=vcvt
