Hi,
Assorted updates to existing tests to compensate for codegen changes
introduced with the gimple-folding of unaligned vector loads and stores.
Regtest clean across assorted Linux systems (p6-p9).
OK for trunk?
Thanks,
-Will

* gcc.target/powerpc/p8-vec-xl-xst-v2.c: New.
* gcc.target/powerpc/p8-vec-xl-xst.c: Disable gimple-folding.
* gcc.target/powerpc/swaps-p8-17.c: Same.
