Assertion failure: !ti->stackTypeMap.matches(ti_other->stackTypeMap), at jstracer.cpp:2730
Posted patch proposed fixSplinter Review
When attempting to re-stabilize because of unpromotable slots, also mark as unpromotable any slots which were double to begin with.

Note: I expect this assertion to rear up a few more times.  I'm trying to get all the easy cases -- resorting to the oracle in any aggressive manner is a 10-15ms perf loss on my machine.
