wasm2js: ignore implicit traps (#2079)
We don't actually try to emit traps for loads, stores, invalid float to ints, etc., so when optimizing we may as well do so under the assumption those traps do not exist.
This lets us emit nice code for a select whose operands are loads, for example - otherwise, the values seem to have side effects.
