Vectorization was disabled for all integer types on aarch64 because it made `round(Int64)` 20% slower: NEON has no 64-bit multiply-high, so each lane goes through general purpose registers. Narrower types use widening multiplies instead, and `llvm-mca` predicts 4x to 20x fewer cycles per element on Neoverse V1. Keep it disabled for 64 bits and up. The perf test keeps one query per distinct code path, adding `Int32` and `Float32`, since only 10 random queries run per test. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
