Backport cfispan.diff to gcc-4.8.3

Attempt to backport cfispan.diff from

https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02625/cfispan.diff

referenced from comment #4 here, to gcc-4.8.3 which we are using for ppc e500v2

So far as I've been able to determine so far, it works for us, passing the
repro mentioned elsewhere in this bug and also the similar repro I had
developed, and not introducing other unexpected changes.  In combination with
the msg2504.html backport also attached.

gcc-4.8.4 code in the vicinity of this patch is nearly identical with 4.8.3.
