	* sem_util.ads, sem_util.adb (Might_Raise): New function
	that replaces Is_Exception_Safe, but has the opposite
	sense. Is_Exception_Safe was missing various cases -- calls inside
	a pragma Debug, calls inside an 'if' or assignment statement,

	that can raise.

	Is_Exception_Safe with "not Might_Raise". Misc cleanup (use

	Is_Protected_Subp_Body. A protected_body is something different
	in the grammar.

2016-10-12  Bob Duff  <duff@adacore.com>

	* sem_case.adb (Check_Choice_Set): Separate
	checking for duplicates out into a separate pass from checking
	full coverage, because the check for duplicates does not depend
	on predicates. Therefore, we shouldn't do it separately for the
	predicate vs. no-predicate case; we should share code. The code
	for the predicate case was wrong.
