introduce future-compatibility warning for forbidden lint groups We used to ignore `forbid(group)` scenarios completely. This changed in #78864, but that led to a number of regressions (#80988, #81218). This PR introduces a future compatibility warning for the case where a group is forbidden but then an individual lint within that group is allowed. We now issue a FCW when we see the "allow", but permit it to take effect. 2021-01-30 00:06:00 +00:00			`// Regression test for #80988`
