[PATCH] D38453: [dwarfdump] Verify that unit type matches root DIE

[Jonas Devlieghere via Phabricator via llvm-commits]

JDevlieghere created this revision.

This patch adds two new verifications:

- Check that the root DIE of a CU is actually a valid unit DIE. (based on its tag)
- For DWARF5 which contains a unit type int he CU header, check that this matches the type of the unit DIE.
