The frame object has a number of fields which belong to the generator object.
By creating a CoState struct, these fields can be moved to generator/threadstate where they belong.

The interpreter no longer has to swap around exception state whenever generators are entered/exited.
The frame object is made more compact, reducing allocation/deallocation overhead (although benchmarking showed no significant difference) 

The attached patch reduces the code base by about 50 LOC overall.
