We introduce high-level typed load elimination for wasm. It is based
on CSALoadElimination. It operates on wasm struct.set/get and
array.length operators (with array operations pending). Wasm types are
used to refine the may-alias analysis ran for stores.
Drive-by:
- Type more nodes in wasm-compiler and wasm-gc-operator-reducer.
- Remove an unsafe-cast test which now hits an Unreachable Turbofan
node.
