Conditional operator bugs

[john-h-kastner]

I've noticed two similar issue with conditional expressions. In both cases, clang does not believe the conditional is checked even though the branches are checked on their own.

void foo(void) {
  int a, b;
  _Ptr<int> c = 0 ? &a : &b;
}

z.c:3:17: error: expression has unknown bounds, cast to ptr<T> expects source to have bounds
  _Ptr<int> c = 0 ? &a : &b;

void f(void) {}
void g(void) {}
void bar(void) {
  _Ptr<void(void)> h = 0 ? f : g;
}

y.c:5:24: error: cannot guarantee operand of cast to checked function pointer type '_Ptr<void (void)>' is a function pointer
  _Ptr<void(void)> h = 0 ? f : g;
                       ^~~~~~~~~
