Backports to gcc 6.x

Backports to gcc 6.x

[Kelvin Nilsen]

I would like to backport the following patches to the GCC 6 branch.

PR66669: Fix failure of gcc.dg/loop-8.c on Power
  https://gcc.gnu.org/ml/gcc-patches/2017-01/msg01788.html

PR68972: g++.dg/cpp1y/vla-initlist1.C test case fails on power
  https://gcc.gnu.org/ml/gcc-patches/2017-02/msg00541.html

Handle conflicting target options -mno-power9-vector and -mcpu=power9
  https://gcc.gnu.org/ml/gcc-patches/2017-03/msg01192.html

PR80103: Fix ICE with cross compiler
  https://gcc.gnu.org/ml/gcc-patches/2017-03/msg01335.html

PR80101: Fix ICE in store_data_bypass_p
  https://gcc.gnu.org/ml/gcc-patches/2017-04/msg00953.html


Each of these patches has been bootstrapped and regression tested on the
GCC 6 branch.  In backport, patch PR80103 omits certain changes to
existing comments that are not present in GCC6.

Are these patches ok for backporting to GCC 6?
