[Ada] Add guard for making only legal labels unreachable
An entity flag Reachable now only applies to E_Label entities. We had an
appropriate guard for setting this flag, but not for clearing.
Cleanup related to detection of uninitialized scalars with GOTO
statements.
gcc/ada/
* sem_ch5.adb (Analyze_Statements): Only clear Reachable flag on
proper label entities.
