[patch] altivec.md bitwise operations support

[Olga Golovanevsky <OLGA at il dot ibm dot com>]

Similarly to the patch that was committed to the lno branch (
http://gcc.gnu.org/ml/gcc-patches/2004-03/msg00769.html), this patch adds
modelling of one's complement to altivec.md, as well as modelling of
bitwise-and & bitwise-or for additional
data types (previously modelled only for V4SI).

Bootstrapped and passed regression tests on powerpc-apple-darwin7.0.0.

ok for mainline?


thanks,
Dorit, Olga
