Fix a merge-blocks fuzz bug (#1730)
If a block has code after an unreachable element, it makes merging to an outer block tricky - the child block may be unreachable, but the parent have a return type,
(block (result i32)
..
(block
(unreachable)
(nop)
)
)
It's ok to end an unreachable block with a nop, but not a typed one.
To avoid this, if a child block has dce-able code, just ignore it.
