*	[Debuginfo] Prevent CodeGenPrepare from dropping debuginfo references.	Wolfgang Pieb	2018-12-11	1	-0/+75
	This fixes PR39845. CodeGenPrepare employs a transactional model when performing optimizations, i.e. it changes the IR to attempt an optimization and rolls back the change when it finds the change inadequate. It is during the rollback that references to locals were dropped from debug value intrinsics. This patch reinstates debuginfo references during rollbacks.
