Michael Munday bb2740e540 IRGen: fix enum bit packing on big-endian platforms. ...

This change modifies spare bit masks so that they are arranged in
the byte order of the target platform. It also modifies and
consolidates the code that gathers and scatters bits into enum
values.

All enum-related validation tests are now passing on IBM Z (s390x)
which is a big-endian platform.
