This patch corrects issues in the compiler whereby default initializing
a protected type component of an access type containing controlled parts
with an allocator causes a crash at compile-time at the point of an
object declaration of such protected type.

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

gcc/ada/

	* exp_ch7.adb (Make_Final_Call): Detect expanded protected types
	and use original protected type in order to calculate
	appropriate finalization routine.
