Is this because we haven't generated entry/exit thunks for `__kmp_invoke_microtask` anywhere if we write it in assembly?
If that's the case, as a simple fix, can we not just eg call the function implemented in assembly `__kmp_invoke_microtask_arm64ec_native` and write in C:
```
void __kmp_invoke_microtask(...) {
  __kmp_invoke_microtask_arm64ec_native(...);
}
```
which should get the entry/exit thunks generated?
