New submission from Fijal <fijall at gmail.com>:

optimize_GUARD_ISNULL can be called in a situation where op.args[0] has a null 
BoxPtr, but getvalue() returns a non-null ConstPtr. Investigating.

To reproduce, compile pypy-c-jit and run twisted tests (trial twisted crashes 
immediately, due to InvalidLoop raised by optimize_GUARD_ISNULL)
