[PATCH] DWARF2 macro info double start file

[Daniel Berlin]

When I originally added the code, we used to get no start source file for 
the primary source file (or end, for that matter).
Now that we do, this code is no longer needed, and causes two start files 
to be emitted in the macro info.

Okay for mainline and branch?

	* dwarf2out.c (dwarf2out_define): Remove start_source_file call,
	CPP will start the file for us.
