The original reason for this bug, compile-time and code-size growth of SPEC CPU
2006 and Polyhedron on AMD Barcelona with -march=native has been fixed (back
to levels before the -fprefetch-loop-arrays defaulting).  For 4.8, that is.

Backporting not really possible (requires preserving of loop structure), thus
wontfix on the branches.
