Find all the usages of `--enable-experimental-feature` or `--enable-upcoming-feature` in the tests and replace some of the `REQUIRES: asserts` to use `REQUIRES: swift-feature-Foo` instead, which should correctly apply to depending on the asserts/noasserts mode of the toolchain for each feature. Remove some comments that talked about enabling asserts since they don't apply anymore (but I might had miss some). All this was done with an automated script, so some formatting weirdness might happen, but I hope I fixed most of those. There might be some tests that were `REQUIRES: asserts` that might run in `noasserts` toolchains now. This will normally be because their feature went from experimental to upcoming/base and the tests were not updated.
