[PING] [PATCH] fix outstanding -Wformat-length failures (pr77735 et al.)

I'm looking for a review of the patch below:

   https://gcc.gnu.org/ml/gcc-patches/2016-10/msg00043.html

The patch should clean up the remaining test suite failures on
ILP32 targets and also fixes up some remaining issues in the
gimple-ssa-sprintf pass that stand in the way of re-enabling
the printf-return-value optimization.

I'm traveling next week so I'm hoping to enable the optimization
shortly after this patch goes in so that if there's any fallout
from it I can fix it before I leave.

Thanks
Martin
