New Revision: 112406

URL: http://llvm.org/viewvc/llvm-project?rev=112406&view=rev
Log:
Port commit 111841 (djg) from llvm-gcc:
Reinstate the code for emitting an initial debug type for a struct,
to handle the case where the struct is only forward-declared. In
this case, a temporary MDNode is not needed and not desired.
