Alexey Samsonov 4e796d0c9f [tests] Remove "supported-target" in favor of "target-arch" lit features.
Test cases definitely should not care about the complete set of architectures
supported by compiler-rt - they should only care about current
architecture that the test suite was configured for.

Introduce new lit feature to reflect this, and convert tests to use it.
