Issue 7770

D2 code:
import std.ascii: uppercase;
import std.string: maketrans;
void main() {
 static r = maketrans(uppercase, uppercase[0 .. $]);
}
DMD 2.059head:
test.d(4): Error: variable __dollar cannot be read at compile time
test.d(4): called from here: maketrans(cast(const(char[]))uppercase,cast(const(char[]))uppercase[0u..__dollar])

D has no runtime initialization for static variables.
Therefor the initializer must be constant.
The error message could be better though.

--------
Sorry, you're point was obviously that __dollar should be resolvable
at compile time.

Fix issue 7770 __dollar cannot be read at compile time
It is always a CTFE variable, even if in global scope.
