ada: Elide temporary for aliased array with unconstrained nominal subtype
When the array is initialized with the result of a call to a function whose
result type is unconstrained, then the result is allocated with its bounds,
so the array can be rewritten as a renaming of the result in this case too.
gcc/ada/
* exp_ch3.adb (Expand_N_Object_Declaration): Fold initialization
expression of Nominal_Subtype_Is_Constrained_Array constant into
the computation of Rewrite_As_Renaming and remove the constant.
Set it to True for an aliased array with unconstrained nominal
subtype if the subtype of the expression is also unconstrained.
