vcgtq_s64 returns uint64x2_t but vmovn_s64 requires int64x2_t. clang accepts
the implicit conversion via lax vector conversions, but gcc does not. Add an
explicit vreinterpretq_s64_u64 so the code compiles with gcc on aarch64 when
USE_64_BIT=1. This path is otherwise untested in CI (aarch64 matrices use
USE_64_BIT=0; the 64-bit-versions matrix uses amd64 AVX compare16).
