Fix tests under `bazel test -c opt`. (#212)

With certain versions of GCC, `bazel test -c opt ...` failed, apparently
due to a compiler bug.

This change:

1.  Adds a workaround for the GCC bug.
2.  Enables the workaround on versions of GCC known to have the bug.
3.  Documents the bug (in comments).
4.  Enables testing with `-c opt` as part of the commit hook.

Note that the versions covered by #2 are a little wider than may be
technically necessary.  As of the time of writing, this affects all
released versions of GCC from 12.1 through 14.1, but the GCC fix has
been backported to the 12.X and 13.X branches.  It may be possible
to reduce the workaround's scope once those are released.
