ada: Only reject volatile ghost objects when SPARK_Mode is On
SPARK rule that forbids ghost volatile objects is only affecting proof
and not generation of object code. It is now only applied where SPARK_Mode
is On. This flexibility is needed to compile code automatically instrumented
by GNATcoverage.
gcc/ada/
* contracts.adb (Analyze_Object_Contract): Check SPARK_Mode before
applying SPARK rule.
