[PATCH] D63119: hwasan: Add a tag_offset DWARF attribute to instrumented stack variables.

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added a comment.

- Apply tag offset expression to all declares

  This correctly handles the case where we end up with multiple declares pointing to the same alloca because a function was inlined multiple times.
