[Ada] Fix problematic line debug info attached to call to finalizer

["Marc Poulhiès" <poulhies@adacore.com>]

[-- Attachment #1: Type: text/plain, Size: 298 bytes --]

The End_Label is not defined for body nodes so a small tweak is needed.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* gcc-interface/trans.cc (At_End_Proc_to_gnu): Use the End_Label of
	the child Handled_Statement_Sequence for body nodes.
	(set_end_locus_from_node): Minor tweaks.
