[PATCH] DW_TAG_typedef and DW_TAG_structure_type not emitted when typedef is used

[David Blaikie]

  I wonder if there's a more general place we should be handling this? And
  what about non-typedefs used in this context?

  The test case should use filecheck, not grep.

  The comment in emittypedef is a bit obscure.
