[Ada] Improve handling of -gnatD

[Arnaud Charlet <charlet at adacore dot com>]

Tested on i686-linux, committed on trunk

When generating -gnatD output, we produce new slocs into a new source file.
Now, when entities with such slocs are passed to In_Extended_Main_Unit, we
need to be able to map these slocs back to the proper source_file_index.
That requires that the Source_File_Index_Table be properly updated while
the .dg file is being generated.

	* sinput-d.adb (Write_Line): Update the Source_Index_Table after each
	line. This is necessary to allow In_Extended_Main_Unit to provide
	correct results for itypes while writing out expanded source.
	(Close_File): No need to update the source_index_table here since it's
	now done for each line.
