Instead the infrastructure in SA to read command line flags should be used. In addition the value if EnableInvokeDynamic is never used, so I removed that from SA.

Isn't the real problem in the way db is initialized with the values for 
these flags? ie shouldn't db.lookupIntConstant("UseTLAB").intValue() be 
returning the actual value of UseTLAB as it occurs in the VM ?

Also we need a regression test for this as obviously it ain't being 
tested! :(

Thanks,
David
