[PATCH] Add a new pass to compute DWARF path discriminators.

[Diego Novillo]

  This changes the way scopes are generated. When an instruction requires
  a new discriminator, it creates a new lexical block inside the instruction's
  original scope. This new lexical block is then annotated with a new
  discriminator value.

  I'm still not sure if this is the right approach or not, but it seems to
  be doing what I need.
