The front-end drops a freeze node on the floor because it puts the node
into the Condition_Actions of an N_Iteration_Scheme of a FOR loop.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* exp_util.adb (Insert_Actions) <N_Iteration_Scheme>: Check that
it is a WHILE iteration scheme before using Condition_Actions.
