* checks.adb (Ensure_Valid): Do not generate a validity check
within a generated predicate function, validity checks will have

If expression is compile-time known and obeys a static predicate
it must be labelled as static, to prevent spurious warnings and
run-time errors, e.g. in case statements. This is relevant when
the expression is the result of constant-folding a type conversion
whose expression is a variable with a known static value.
