[Ada] Locally enabled invariants are ignored

[Arnaud Charlet]

This patch moves routine Find_Pragma from sem_util to einfo. No change in
behavior, no test.

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

2013-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

	* einfo.ads, einfo.adb: Remove with and use clauses for Namet.
	(Find_Pragma): New routine.
	* sem_util.ads, sem_util.adb (Find_Pragma): Moved to einfo.
