Currently, when the initializer for a variable accesses that variable in CTFE,
it's only indirectly detected via the 'recursion limit exceeded' message.
It should be detected directly.

---
const int q = foo();

int foo() { return q; }
---
rr.d(3): Error: function rr.foo CTFE recursion limit exceeded
rr.d(1):        called from here: foo()
rr.d(3):        1000 recursive calls to function foo
rr.d(3):        while evaluating q.init
rr.d(1):        called from here: foo()
