In PR39807 we incorrectly handle circumstances where calls are common'd from conditional blocks into the parent BB. Calls that can be inlined must always have DebugLocs, however we strip them during commoning, which the IR verifier asserts on. Fix this by using applyMergedLocation: it will perform the same DebugLoc stripping of conditional Locs, but will also generate an unknown location DebugLoc that satisfies the requirement for inlinable calls to always have locations. Some of the prior logic for selecting a DebugLoc is now likely redundant; I'll generate a follow-up to remove it (involves editing more regression tests).
