This was:

Author: Eric Christopher <echristo at apple.com>
Date:   Fri Jul 27 22:00:05 2012 +0000

    Add a DW_AT_high_pc for CUs that are a single address range. Update
    all tests accordingly.

    Fixes PR13351.

    Patch by shinichiro hamaji!

    git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160899 91177308-0d34-0410-b5e6-96231b3b80d8

for the record. I think ultimately it's the right thing to do, but we seem to have a couple problems to get through first.
