[PATCH] D43824: [CallSiteSplitting] Do not crash when BB's terminator changes.

[Florian Hahn via Phabricator via llvm-commits]

Change doCallSiteSplitting to iterate until we reach the terminator instruction.
tryToSplitCallSite can replace BB's terminator in case BB is a successor of
itself. Then IE will be invalidated and we also have to check the current
terminator.
