           Summary: [safeD] Escaping a reference to a local variable from

int* foo() safe{
    int n;
    int*x=&(0?n:n);
    return x;
}

This currently compiles without error.

(When fixing, make sure that safe functions can still assign to a
ConditionalExpression, afaik it is currently implemented by taking the address
of the 2. and 3. operands.)

Issue 6497 - [safeD] Can take address of local variable through ?:

If the compiler rewrote `&(a ? b : c)` to `&*(a ? &b : &c)`, re-run semantic on
the `AddrExp`s to ensure they don't take addresses of local variables.

Fixes issue 6497
