Here's a first complete implementation.

In this form a ReleaseAsserts dsymutil run on a ReleaseAsserts+modules clang is about 5% slower:

  # trunk
  $ time dsymutil clang   # best out of 3 runs
  
  real	0m46.861s
  user	0m53.870s
  sys	0m4.019s
  
  # with this patch
  
  real	0m48.995s
  user	0m55.888s
  sys	0m4.174s
