Add sed(1) tests for proper behaviour of the G option as fixed in PR 26152,

and for proper behaviour of some sed functions given a nil pattern space,
as fixed in PR 34813.

The test for G was based on the test in the PR.  The nil pattern space test
is slightly different as we need to get *some* output, as the core dump will
also produce no output (old behaviour) and turn up falsely that the utility
is working fine.
