I don't remember which AOT mode it is, but I think for some interpreter modes we still need the AOT image for corlib because it contains some trampolines

ah, that's right. But if I remember right, we only need the aot image for corlib?

If I remember correctly, I think wasm is ok here.

I'm pretty sure dlopen isn't called in the wasm case unless WASM_SUPPORTS_DLOPEN is set to defined? We do appear to do all the probing even when none of this will ever resolve a symbol |

dlopen in emscripten is very expensive, so we should skip probing for AOT modules if we're currently configured for interpreter only, to reduce startup overhead.
