[Polly] Reduced code analyzability moving from LLVM 3.9.0 to 5.0.1
...G now looks very similar to what I got on LLVM
3.9.0 ([1] vs [2]).
Any idea why setting -simplifycfg-sink-common=false is necessary?
Similar to LLVM 5.0.1, the default for 3.9.0 is true [3], and setting it
to false wasn't necessary in the latter version.

...seem to have
effect on the hot paths.
Can anyone give me some pointers on how to fix this? Or could this be a
regression in Polly?
Thanks!
