The compiler should report an error when the upper bound of register binding is larger than UINT32_MAX:
```
RWBuffer<float> Buf[10] : register(u4294967294); // UINT32_MAX - 1
[numthreads(1, 1, 1)]
void main() {
Buf[1][0] = 0;
}
```

**Current behavior:**
Clang with `-Od` ignores the binding (resource is not bound).
Clang without `-Od` crashes in `OpLowerer`.
DXC does not report an error if the register range starts at `UINT32_MAX - 1` and it overflows the register slot.
DXC with register range starting at `UINT32_MAX` ignores the binding and assigns the resource `u0`.
