Make comparisons between region pointers work Region pointers were considered a scalar type, so compare_scalar_type would get called to compare region pointers in trans. This would fail, since compare_scalar_type has no case for region pointers. Changed type_is_scalar to return false for region pointers. This had the side effect of breaking casts to types of the form &T. To ameliorate that, I added library functions ptr::assimilate (taking a &T to a *T) and ptr::to_uint (taking a &T to a uint), both of which use reinterpret_cast. While I was at it, I removed ty::type_has_resources, which is dead code. 2012-08-02 16:23:04 -05:00			`debug!{"&x=%x", ptr::to_uint(&x)};`
