Some platforms (like non-Emscripten WebAssembly) do not have the concept of a "return address" in the same way that other platforms do, and `__builtin_return_address` is unavailable.
This change makes `-fsanitize=address` available for WASI target by replicating what we do for Emscripten because they share the same memory model.

The `.syms` files are passed to the linker with `--dynamic-list=` if the file exists, but the linker option is not supported on wasm-ld.
