[DebugInfo@O2][Utils] Undef instead of delete dbg.values in helper func
Summary:
Related bug: https://bugs.llvm.org/show_bug.cgi?id=40648
Static helper function rewriteDebugUsers in Local.cpp deletes dbg.value
intrinsics when it cannot move or rewrite them, or salvage the deleted
instruction's value. It should instead undef them in this case.
This patch fixes that and I've added a test which covers the failing test
case in bz40648. I've updated the unit test Local.ReplaceAllDbgUsesWith
to check for this behaviour (and fixed a typo in the test which would
cause the old test to always pass).
