[PATCH] RS6000 : Fix insvsi_internal1


insvsi_internal1 pattern incorrectly calculates last operand.
This is exposed by the test case attached.

       * config/rs6000/rs6000.md (insvsi_internal1): Fix operand[1].
       * g++.dg/opt/20050511-1.C: New test.

Bootstrapped and tested on powerpc-darwin.
OK?

Thanks,
