This series fixes a number of problems in the rs6000 backend, building on top of https://gcc.gnu.org/ml/gcc-patches/2015-06/msg01396.html. Patch 5,6,7 really need the fixed rtx_cost function to be applied first, the others are independent of that change (if you're willing to allow a failing testcase).
Bootstrapped and regression tested powerpc64le-linux and powerpc64-linux.
