Remove GADT refinements, part 4 - MkId.mkRecordSelId only used a special case of refineGadt, which doesn't need full unification. That special case is now implemented as TcGadt.matchRefine and TcGadt.refineGadt can finally go.

Release some of the memory allocated to a stack when it shrinks (#2090) When a stack is occupying less than 1/4 of the memory it owns, and is larger than a megablock, we release half of it. Shrinking is O(1), it doesn't need to copy the stack.

Updating a thunk in raiseAsync might encounter an IND; cope There was already a check to avoid updating an IND, but it was originally there to avoid a bug which doesn't exist now. Furthermore the test and update are not atomic, so another thread could be updating this thunk while we are. We have to just go ahead and update anyway - it might waste a little work, but this is a very rare case.
