Add version 52.0 in ASM to support JDK 8 classfiles
Accept classfiles with major version 52 for JDK 8

Is it possible to add this new version support? IntelliJ IDEA is dependent on
ASM 4, but since the new class file version was merged into lambda repository,
it makes it difficult to use newer lambda builds with Intellij due to this bug
(http://youtrack.jetbrains.com/issue/IDEA-95473).
Attaching a patch that adds support for version 52 in ASM. I haven't tested it,
hope someone can look into this.
