Use message-passing to implement throwTo in the RTS This replaces some complicated locking schemes with message-passing in the implementation of throwTo. The benefits are - previously it was impossible to guarantee that a throwTo from a thread running on one CPU to a thread running on another CPU would be noticed, and we had to rely on the GC to pick up these forgotten exceptions. This no longer happens. - the locking regime is simpler (though the code is about the same size) - threads can be unblocked from a blocked_exceptions queue without having to traverse the whole queue now. It's a rare case, but replaces an O(n) operation with an O(1). - generally we move in the direction of sharing less between Capabilities (aka HECs), which will become important with other changes we have planned. Also in this patch I replaced several STM-specific closure types with a generic MUT_PRIM closure type, which allowed a lot of code in the GC and other places to go away, hence the line-count reduction. The message-passing changes resulted in about a net zero line-count difference.
