[Ada] Do not generate useless length check for array initialization
2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
gcc/ada/
* checks.ads (Apply_Length_Check_On_Assignment): Declare.
* checks.adb (Apply_Length_Check_On_Assignment): New procedure
to apply a length check to an expression in an assignment.
* exp_ch5.adb (Expand_Assign_Array): Call it instead of calling
Apply_Length_Check to generate a length check.
* sem_ch5.adb (Analyze_Assignment): Likewise.
