This patch only renames ScopInfo class to ScopBuilder. This change is required because ScopBuilder class only creates SCoP objects, it is not a container class to store them. Valid SCoP objects will be contained in ScopInfoRegionPass and ScopInfoWrapperPass.
Depends on D20770
Maybe we should also rename this member from SI to SB then, to avoid confusion. I apologize for commenting after this patch has already been merged, unfortunately I've noticed this too late.
