[svn r102] Further delayed emission of function bodies to avoid problems with circular-forward-references. Now uses the DMD _adEq(void[], void[], TypeInfo) runtime function for array equality comparison.

module bug1;
struct Foo { Foo opSub(ref Foo b) { return Foo(); } }
struct Bar { Foo whee; }
void test(ref Bar moo) { Foo nngh; auto plonk = nngh - moo.whee; }
void main() { Bar bar; test(bar); }
