ada: Convert -gnatw.n messages to warnings

Previously the messages produced by this warning switch
were info messages that were suppressed with the same
methods as regular warnings. Since info messages are now
separated as a completely different class of messages then
these messages should be converted back to warnings in order
for the previous pragma based suppression methods to work.

gcc/ada/

	* doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update
	documentation for -gnatw.n switch.
	* exp_util.adb: Convert info messages into warnings.
	* gnat_ugn.texi: Regenerate.
