Added static analysis of blocks when inlining. Allow inlining only when block is functional ...i.e., does not access any shared state (in instance or class variables). If the block does a self-send, the sent method has to be (transitively) functional too. To allow for self-sends in action blocks, copy (transitively) self-sent methods to target parser. This is safe as these self-sent methods are guarnateed to be functional.
