Merge-Blocks improvements (#1760)
Previously we didn't try to merge a block into the parent if the block had a name. This lets us merge part of it, that is:
(block
(..a..)
(block $child
(..b..)
(.. some br to $child ..)
(..c..)
)
)
=>
(block
(..a..)
(..b..) ;; moved out
(block $child
(.. some br to $child ..)
(..c..)
)
)
This is beneficial for 2 reasons: the child may now be a singleton, so we can remove the block; or, now that we canonicalized the br-containing code to the head of the child, we may be able to turn it into an if.
