Reorg AltiVec detection code

+ advertise that full AltiVec SIMD acceleration is now available on
OpenBSD.

The relevant compilers probably all support C99 or GNU's variation of
C90 that allows variables to be declared anywhere, but our policy is to
conform to the C90 standard, if for no other reason than that it
improves code readability.
