The deoptimization environment of AssertAssignable should not have it's inputs in it, since those get poped before the call to the TypeTestingStub. A lazy deopt should therefore continue in unoptimized code after the TTS call, without the inputs. This was discovered by running many lightweight isolates concurrently on the JIT. To simplify a regression test we'll add new VM flags that can trigger deoptimization on any runtime call (optionally filtered by name of runtime call). We can use this mechanism to possibly discover more bugs of the same kind.
