[PATCH] D29902: [BranchFolding] Update debug location along with the update of branch instruction.

[Taewook Oh via Phabricator via llvm-commits]

twoh created this revision.

Currently, BranchFolder drops DebugLoc for branch instructions in some places. For example, for the test code attached, the branch instruction of 'entry' block has a DILocation of

  !12 = !DILocation(line: 6, column: 3, scope: !11)

, but this information is gone when then block is lowered because BranchFolder misses it. This patch is a fix for this issue.
