JDK-8205645 - Bump maximum recognized class file version to 57 for JDK 13
Description
Each JDK platform release define a class file format whose major version is one greater than the last.

For JDK 14, the maximum recognized class file version should be 58.
Comments
No actual change is needed in hotspot to bump the max version. The max comes from a define set by the build system based on the version-numbers file. All we do in hotspot is add a new #define for the current JDK version, but even that isn't essential as nothing uses it at the version change. We'd only need it if checking for something specific to the new classfile version.
