[liftoff] Add regression test for asan dcheck failure

Adding a regression test for https://crrev.com/c/1930606.

This test was generated using --dump-wasm-module, which created a 6KB
module, and then running binaryen's wasm-reduce on it until it churned
this out, and removing an extra kExprUnreachable.
