3779 ["123"][0][$-1] causes __dollar unresolved in compile-time.

After constant folding the array, we should see if we now know __dollar.

Ensure compile-time constants are not variables(!)

This fixes a serious structural problem: if a runtime variable is used where
a compile-time constant is required, it will most likely still compile. But
the code will be wrong. The root cause for this is an inconsistency in the
meaning of optimize(WANTinterpret). It has two meanings:
(A) In the CTFE engine, and throughout most of the compiler, WANTinterpret is
used when an actual compile-time value is required.
(B) But in a few places, it just means that it's permissible (but not
mandatory) to use CTFE. This actually doesn't make sense -- if it hits a call
statement, it WILL interpret, and if that fails, it will generate an error
message.

The silent errors happen in optimize.c, fromConstInitializer(). I've changed it to give an error message when the variable isn't a constant.

* dsymbol.c: when setting $ for a const variable, don't interpret.
 (the patch to 3779 is a much better solution).

There are three places which were WANTinterpret, but had special treatment
when the result wasn't a variable. They are:
* mtype.c: static arrays. A[N] could be a template parameter.
* statement.c: case statements are allowed to be global variables initialized
in 'static this'.
* template.c, genIdent(): a template expression could actually be an alias
parameter.
In each case, I changed it to do a const-fold (WANTvalue), then do the check
for TOKvar, and then do optimize(WANTinterpret).

* semanticTiargs(). This is yucky. _traits does bad things.
int i;
__traits(isArithmetic, i+2, i);
What the heck is i+2 as a template parameter? It's not a value (i is a runtime
variable). It's not an alias. It's not a type.
The optimize(WANTinterpret) is silently failing to interpret i, but __traits
only needed the type anyway. Fortunately, in semanticTiargs, flags is 1 if
and only if it's called from __traits. So I just do a constant fold, instead
of an interpret.

This fixes bug 1880 "templates instantiated with non-constants should fail sooner", and MANY others.

4298 Constant array translated to unnecessary array literal creation

Uses rsinfu's patch, which works once the patch for bug 3779 is included.
I also need to make a little change to CTFE, which can no longer assume that
const variables have been expanded. This triggered one failure in Phobos --
but it was a bug:
immutable int[1] x =[7];
void main(){ int [] y = x;} // passed, now correctly generates an error

Fix zero-sized fields in struct initializers

For things like:
struct S { union { int a; int[0] b; int c;} }
we need to recognize that a and c are part of the same union. We need to
check the size as well as the offset.
