`swift test` should have more flexible test selection

I'm using a Makefile for a few projects where `make test` runs `swift test`. I'd like to be able to exclude a few tests (hardware-specific) by default, and have other Makefile targets like `make testhw` to run the full set.

The --filter CLI option doesn't seem to be flexible enough to either exclude tests or specify multiple filter patterns.

$ swift test --filter FuzzerTests --filter MemoryTests --filter PCITests

Will only run the last filter pattern specified - PCITests. Either allowing the specification of multiple filters, or adding an --exclude or similar option would do what I need, but I think both would be useful.
