[svn r111] Fixed most problems with complex number support and added typeinfo for them. Added typeinfo ti_C. Did some changes to the way expressions that have both lvalue and rvalue LLVM values are handled.

module foreach6;

struct S
{
    long l;
    float f;
}

void main()
{
    S[4] arr = void;
    foreach(i,v;arr) {
        v = S(i, i*2.5);
    }
}
