In a `For_set` destination, a temporary can be reused only if it always used with the same type. Otherwise, typing of Cminor code fails later in the compilation pipeline. This commit implements temporary reuse if and only if the typing constraint is respected. - For `&&` and `||`, it avoids the possibility of wrong reuse (as reported in #453). - For nested conditional expressions, it improves a bit the generated code by reusing the temporary when possible. Fixes: #453
