[PATCH] rs6000: Builtins for doubleword compare should be in [power8-vector] (PR103625)

[Bill Schmidt via Gcc-patches]

Hi!

PR103625 observes that we ICE when doing vector compares on doublewords.
The original built-in function support requires Power8 vector support for
these, but this was missed in the new built-in support.  Moving these
functions to the [power8-vector] stanza solves the problem.

Tested the fix on a powerpc-e300c3-linux-gnu cross.  Bootstrapped and tested on
powerpc64le-linux-gnu with no regressions.  Is this okay for trunk?

Thanks!
Bill
