[PATCH, testsuite]: Fix g++.dg/mv[1,6].C failure with non-default architecture

[Uros Bizjak]

Hello!

2012-11-16  Uros Bizjak  <ubiz...@gmail.com>

        * g++.dg/mv1.C (dg-options): Add -march=x86-64.
        * g++.dg/mv6.C (dg-options): Ditto.

Tested on x86_64-linux-gnu {,-m32} configured --with-arch=corei7-avx
and committed to mainline SVN.

Uros.
