RFR: 8287491: compiler/jvmci/errors/TestInvalidDebugInfo.java fails new assert: assert((uint)t < T_CONFLICT + 1) failed: invalid type #

[Yasumasa Suenaga]

We saw new assertion error after [JDK-8286562](https://bugs.openjdk.java.net/browse/JDK-8286562) ( #8646 )


# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (/home/ysuenaga/github-forked/jdk/src/hotspot/share/utilities/globalDefinitions.hpp:735), pid=2619, tid=2635
#  assert((uint)t < T_CONFLICT + 1) failed: invalid type


It was caused by passing `JavaKind.Illegal` to slot kind at TestInvalidDebugInfo.java . We should pass `JavaKind.Void` instead of `JavKind.Illegal`.

See JBS for more details (I attached hs_err log).
