math.vectors.simd.intrinsics: fix deploy bug
...
If not called with a known-at-compile-time SIMD type, the intrinsic definitions were leaving behind runtime quotations that referenced the c-array words after c-type information had been stripped, causing deployed applications that used SIMD to fail.

math.vectors.simd: add vcount to the tests

Also add a base case to (approx=) for integer returns. vcount returns an integer even for float vector inputs, but the test machinery isn't smart enough to figure that out and uses (approx=) on the outputs anyway.
