[svn r312] Changed assert codegen to insert an unreachable terminator after the call to the assert function, which currently calls abort(). Changed array comparison runtime support to pass the array typeinfo instead of the element typeinfo. This allows a cleaner and faster implementation.

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); }
