Hi Vivek,

The changes in is_intrinsic_disabled in compilerDirectives.* are static 
and only access the command line flag DisableIntrinsics. As long as 
stubs are only generated during startup and don't have a method context 
- that is ok - but it doesn't belong in the compilerDirectives-files if 
it doens't use directives.
