Split off from bug 9744.
Applies to both shared and __gshared, (or any static variable in D1).
-------
shared int x1;
shared(int) * foo() { return & x1; }
shared int *p1 = & x1; // OK
shared int *p2 = foo(); // ERROR - & x1 is not valid in CTFE.
-------
Obviously, any attempt to dereference &x1 must fail.
Likewise, it must not be valid to take the address of a thread-local variable.
This is the largest remaining difference between constant-folding and CTFE.
