RFR: (S): SA: clhsdb 'where -a' throws Assertion Failure with illegal code 236 when CDS is used

[Ioi Lam]

HI Jini,

[1] "_nofast_aload" should be "_nofast_aload_0": aload and aload_0 are 
two different bytecodes.

[2] Only the _nofast_aload_0 bytecode is tested. For completeness, do 
you think it makes sense to add test cases for these other 3 bytecodes?

     _nofast_getfield
     _nofast_putfield
     _nofast_iload


Thanks
- Ioi
