Introduce splitBlock and use it in splitEntryBlockForAlloca
RegionInfo::splitBlock did not update RegionInfo correctly. Specifically, it tried to make the new block the entry block if possible. This breaks for nested regions that have edges to the old block.
We simply do not change the entry block. Updating RegionInfo becomes trivial as both block will always be in the same region.
splitEntryBlockForAlloca makes use of the new splitBlock.
