RFR: JDK-8245432: Lookup::defineHiddenClass should throw UnsupportedClassVersionError if the given bytes are of an unsupported major or minor version

[Mandy Chung]

Lookup::defineHiddenClass currently throws IAE by ASM if the given bytes 
are of unsupported class file version.  The implementation should catch 
and throw UnsupportedClassVersionError instead.

This patch also includes a spec clarification of @throws IAE if the
the bytes has ACC_MODULE flag set to fix JDK-8245596.
