ALTIVEC and VSX features are not default in the POWER CPU feature sets because they are intended to be enabled by firmware. They should be added individually to the CPU_FTRS_POSSIBLE set. It already contains CPU_FTR_VSX, so add ALTIVEC. This becomes important with a reduced set of supported CPUs.
The _COMP features should be used because they won't be present if compiled out.
