This plugs a loophole in the change improving code generation for nested
aggregates present in conditional expressions: once the delayed expansion
is chosen for the nested aggregate, the expansion of the parent aggregate
cannot be left to the back-end and the test must be adjusted to implement
this in the presence of conditional expressions too.

gcc/ada/

	* exp_aggr.adb (Expand_Record_Aggregate.Component_OK_For_Backend):
	Also return False for a delayed conditional expression.

Tested on x86_64-pc-linux-gnu, committed on master.
