checkasm: ipred: Test and benchmark FILTER_PRED separately for 10 and 12 bpc

This allows testing cases where this function internally switches
between two implementations for those two, without adding a bpc
argument to the init function (forcing testing and benchmarking every
16 bpc ipred function twice).
