Thanks for fixing this. LGTM without the change that moved Red outside the enum. I also had a couple notes

[cachemeifyoucan]

The correct spelling for the requirement is REQUIRES: aarch64-registered-target, not arm64.

Just like @dsandersllvm says, if the test is put in a sub directory that has the name of the target, usually you just put the requirement in the lit.local.cfg in that directory. You just need to follow the file example like: https://github.com/apple/llvm-project/blob/next/llvm/test/CodeGen/AArch64/lit.local.cfg so you don't need to repeat the require line in each test.
