ada: Reject ambiguous function calls in interpolated string expressions
When the interpolated expression is a call to an ambiguous call
the frontend does not reject it; erroneously accepts the call
and generates code that calls to one of them.
gcc/ada/
* sem_ch2.adb (Analyze_Interpolated_String_Literal): Reject
ambiguous function calls.
