--- Comment #1 from Matthias Kretz (Vir) <kretz at kde dot org> ---
I already posted a fix on the gcc-patches and libstdc++ lists:
libstdc++-v3/ChangeLog:
* include/experimental/bits/simd.h: Remove unnecessary static
assertion. Allow sizeof(8) integer __intrinsic_type to enable
the necessary mask type.

That was a thinko: the fact that a certain set of instructions doesn't exist on
POWER7 doesn't imply that the type isn't usable. The static_assert was simply
wrong.
