Bug 9745 – Allow non-thread local static variables to have their address taken in CTFE

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.

It's already supported in the const-folding code, now support it in CTFE as well. This commit adds full support for pointer arithmetic.
