[Bug c++/36685] New: clarify/diagnose use of weak constant

[algrant at acm dot org]

Consider this:

  __attribute__((weak)) extern int const K = 7;
  int f(void) { return K; }
  int a[K];

Assuming the combination of 'weak' and 'const' is legitimate
(and it seems useful enough to allow), the compiler should avoid
the constant-promotion optimization when generating f(), and
should fault a[].
