Also asserts on x86. Pretty sure the assert is just bogus. We have a JSOP_POS with input int32 and output double, I didn't know that was possible but there are probably some edge cases where we remember the output type. Investigating.

When we GC, TI remembers the type of values monitored in the interpreter (double here). In this case we can have a JSOP_POS with types int32 -> double. I verified that we get the same types with JM+TI. So the assert is indeed bogus, the patch just relaxes it a bit.
