[Ada] Errors missed on ACATS test B650007
This ACATS test shows that we need to call Is_Immutably_Limited_Type
in Analyze_Function_Return and also that we have a latent bug in
Is_Immutably_Limited_Type which shouldn't look through private types.
gcc/ada/
* sem_aux.adb (Is_Immutably_Limited_Type): Do not look through
private types as per RM 7.5(8.1).
* sem_ch6.adb (Analyze_Function_Return): Use
Is_Immutably_Limited_Type as per RM 6.5(5.10).
