HEAD. Enable VIMAGE in GENERIC kernels and some others (where GENERIC does not exist) on HEAD. Disable building LINT-VIMAGE with VIMAGE being default. This should give it a lot more exposure in the run-up to 12 to help us evaluate whether to keep it on by default or not. We are also hoping to get better performance testing. The feature can be disabled using nooptions. Requested by: many Reviewed by: kristof, emaste, hiren X-MFC after: never Relnotes: yes Differential Revision: https://reviews.freebsd.org/D12639
