[PATCH] D54590: [compiler-rt][UBSan] Sanitization for alignment assumptions.

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri updated this revision to Diff 174452.
lebedev.ri added a comment.

Adapt with the actual pointer no longer being provided, compute it by subtracting the offset.
While there, also display the misalignment offest (the result of the `real pointer  &  aligment mask`).
