We are incorrectly rearranging 32-bit words inside a 64-bit typed value for big endian systems, which would result in never marking a virtual interrupt as inactive on big endian systems (assuming 32 or fewer LRs on the hardware). Fix this by not doing any word order manipulation for the typed values.
