[svn r76] Fixed: TypeInfo for structs. Fixed: PostExp was unable to allocate storage for parameters. Fixed: Many types of functions and delegates were broken. Misc cleanups.

module foreach6;

struct S
{
    long l;
    float f;
}

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