Do not attempt to preserve DWARF if a previous pass removes it (#3887)
If we run a pass that removes DWARF followed by one that could destroy it, then
there is no possible problem - there is nothing left to destroy. We can run the later
pass with no issues (and no warnings).
Also add an assertion on running a pass runner only once. That has always been
the assumption, and now that we track whether the added passes remove debug
info, we need to check it.
Fixes emscripten-core/emscripten#14161
