[PATCH] D57962: [DebugInfo] PR40628: Don't salvage load operations

[Jeremy Morse via Phabricator via llvm-commits]

jmorse added a comment.

Folded last comments into commit, but phab doesn't show those comments inline because of path differences it seems:

- Added comment warning against salvaging loads in salvageDebugInfoImpl
- Removed TBBA metadata and un-necessary DILocations
- New test case positively checks for an undef dbg.value corresponding to the optimised-out load.
