Test case: JSOP_GETGNAME with TI.
This error is tripping frequently in the OSR branch, but can be reproduced on master with the attached test case. The IonBuilder is attempting to create an MUnbox instruction to act on MLoadSlots, which is Type_Int32.
Test case must be run with "--ion -n" to reproduce.
