Subject: [Ada] Compiler crash on large array aggregate
Authentication-results: sourceware.org; auth=none

This patch fixes a bug in which the compiler crashes if the number of
subcomponents in an array aggregate is 2**31 or more.

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

2017-04-25  Bob Duff  <duff@adacore.com>

	* exp_aggr.adb (Component_Count): Protect the
	arithmetic from attempting to convert a value >= 2**31 to Int,
	which would otherwise raise Constraint_Error.
