How sure are you about this? Shouldn't clocklo go into dst[0] and
clockhi go into dst[1]? This is confirmed by
"""
clock2x32ARB() returns
the same value encoded as a two-component vector of 32-bit unsigned integers
with the first component containing the 32 least significant bits and the
second component containing the 32 most significant bits.
"""
Did the tests fail without that? Perhaps that indicates something else is wrong?
