The path in Expand_N_If_Expression implementing the special optimization for
an unidimensional array type and dependent expressions with static bounds
fails to call Process_Transients_In_Expression on their list of actions.
gcc/ada/
* exp_ch4.adb (Expand_N_If_Expression): Also add missing calls to
Process_Transients_In_Expression on the code path implementing the
special optimization for an unidimensional array type and
dependent expressions with static bounds.
Tested on x86_64-pc-linux-gnu, committed on master.
