Yeah I'll have to change the flags so that multi-hit mode is enabled as an
option to -z. Like -z1 enables OpenCL in single-hit mode and -z2 enables
OpenCL in multi-hit mode. I made the kludge originally because I hadn't
figured where to hook into OpenCL.
I think this is enabled/disabled in the original code with ap->a_nobooleans
= 1 and ap->a_onehit = 1 or something like that.
