[LLVMdev] Preserve RegionInfo after regionsimplify

[Vu Le]

Hi Tobias,
My RegionSimplify pass adds new exit node for refined regions to convert
them into simple region.
However, the RegionInfo pass does not seem to recognize those changes.
For example, in the attached file, bb4.region is supposed to be in the first
region.

My RegionExtractor pass required the extracted region to be simple.
Should we modify RegionInfo or is their away to preserve the RegionInfo from
RegionSimplify and pass it to RegionExtractor?
Thanks.
Vu
