RFR: 8205998: [lworld] Verifier should reject value type classes if -XX:+EnableValhalla is not set

[Harold David Seigel]

Hi,

Please review this LWorld fix that throws a ClassFormatError exception 
if a class is a value type class and -XX:+EnableValhalla is not set.

The fix was tested with tier1 and tier2 tests on Linux x64 and Macosx.

Thanks, Harold
