[PATCH] D85670: [Instruction] Add updateLocationAfterHoist helper

[Vedant Kumar via Phabricator via llvm-commits]

vsk updated this revision to Diff 293896.
vsk added a comment.

- To drop the location of a call within a function with no subprogram, set an empty DebugLoc instead of trying to preserve scope/inlinedAt info. Update a unit test accordingly.
