[Wasm] Unreachable end ops don't widen result types

Reviewed by Yusuke Suzuki.
In [email protected] we fixed how result types were
pushed onto the wasm value stack, widening them to the expected type
rather than the last predecessor's type at the merge.
This missed the case for unreachable expressions in the block, which
is fixed in this patch.
