clang definitely doesn't have all the data already in memory, it has just a
single translation unit in memory at a time.
So, such a .debug_names is completely useless, because then you don't have
one index, but hundreds if not thousands of them that all needs to be
queried for the same information.
That is why the index should be added by linkers or post-link tools.
And, if LLDB can cope only with clang generated .debug_names and can't deal
with .debug_names generated by other tools, something is seriously wrong.
