RFR: version specific class file parser and verifier fixes

[Harold David Seigel]

Hi,

Please review this LWorld change to ignore the ValueTypes attribute and 
value type specific access flags for class file versions < 55.  This fix 
also includes changes to the verifier to throw VerifyError exceptions 
for withfield and defaultvalue opcodes for class file versions < 55.

The changes were tested with various tier1 - tier5 Mach5 tests on Linux 
and Mac.

Thanks, Harold
