```
AstGen: coerce break operands of labeled blocks

Similar code was already in place for conditional branches. This updates
AstGen to do the same for labeled blocks. It takes advantage of the
`store_to_block_ptr` instructions by mutating them in place to become
`as` instructions, coercing the break operands before they are returned
from the block.

```
