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.

https://github.com/D-Programming-Language/dmd/commit/aa0ec787714dff32a83d2666eaf3e2e07454e254 Fix issue 9745 Allow &staticvar in CTFE

Use SymOffExp for non-dereferenceable pointers to static variables. It's already supported in the const-folding code, now support it in CTFE as well. This commit adds full support for pointer arithmetic.
