An indirect argument (except `@inout_aliasable`) must not alias with another indirect argument.
Now, if we would replace tempAddr with destAddr in
```
apply %f(%tempAddr, %destAddr) : (@in T) -> @out T
```
we would invalidate this rule.
This is even true if the called function does not read from destAddr.
Fixes a SIL verification error.
