Unreachable typing fixes (#1004)

* fix type of drop, set_local, set_global, load, etc: when operand is unreachable, so is the node itself

* support binary tests properly in test/passes

* fix unreachable typing of blocks with no name and an unreachable child

* fix continue emitting in asm2wasm

* properly handle emitting of unreachable load
