Problems with vdefault/vwithfield

[Tobias Hartmann]

Hi,

please review the following fix:
http://cr.openjdk.java.net/~thartmann/valhalla/vt_prototype/webrev.06/

We hit a ShouldNotReachHere in GenerateOopMap::interp1() with "unexpected opcode: 215" because the _vwithfield bytecode is not known. I fixed the same problem in MethodLiveness::BasicBlock::compute_gen_kill_single() and BCEscapeAnalyzer::iterate_one_block() and modified the tests to trigger this.

Thanks,
Tobias
