I tried running the symbolizer on a patch build backtrace. The patch build did not include the generate_buildid_to_debug_symbols_mapping task, so the symbolizer failed. It would be nice if the symbolizer worked on most/all PB backtraces so that SERVER engineers can confidently use the symbolizer for any backtrace.

This could be achieved by adding the generate_buildid_to_debug_symbols_mapping functionality to "generate resmoke tasks", or something similar.
