[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 typeinfo;

void main()
{
    auto ti = typeid(int);
    char[] str = ti.toString();
    printf("%.*s\n", str.length, str.ptr);
    assert(str == "int");
}
