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.
