gcc/clang reject bit-fields with bit-width larger than the underlying type.
This change enables compilation of the test with gcc/clang.

🚫
This PR failed Diffblue compatibility checks (cbmc commit: d9c36cb).
Build URL: https://travis-ci.com/diffblue/test-gen/builds/96577049
Status will be re-evaluated on next push.
Please contact @peterschrammel, @thk123, or @allredj for support.

Common spurious failures:

  • the cbmc commit has disappeared in the mean time (e.g. in a force-push)
  • the author is not in the list of contributors (e.g. first-time contributors).

The incompatibility may have been introduced by an earlier PR. In that case merging this
PR should be avoided unless it fixes the current incompatibility.

Usual promotion rules apply to bit-fields -- thus, an unsigned bit-field
that is smaller than 'int' gets promoted to 'int', and thus yields a signed
expression. Issue #3709.
