CoerceIntOrPtrToIntOrPtr - Convert a value Val to the specific Ty where both are either integers or pointers.
This does a truncation of the value if it is too large or a zero extension if it is too small.
This behaves as if the value were coerced through memory, so on big-endian targets the high bits are preserved in a truncation, while little-endian targets preserve the low bits.
