[COMMITTED 12/31] ada: Add elaboration switch tags to info messages

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

From: Viljar Indus <indus@adacore.com>

Add the ?$? insertion characters for elaboration
message so they would be marked with the [-gnatel]
tag. Note that these insertion characters were
not added for SPARK elaboration messages:

gcc/ada/

	* sem_elab.adb: Add missing elaboration insertion
	characters to info messages.

Tested on x86_64-pc-linux-gnu, committed on master.
