The debug value live intervals computed by Live Debug Variables may extend beyond the range of the debug location's lexical scope. In this case, splitting of an interval can result in an interval outside of the scope being created, causing extra unnecessary DBG_VALUEs to be emitted. To prevent this, trim the intervals to the lexical scope. This resolves PR33730. Reviewers: aprantl Differential Revision: https://reviews.llvm.org/D35953 llvm-svn: 309933
