I will remove this one here though!

These new tests fail cleanly without expectedly crashing on builds configured for selected targets (e.g. `-DLLVM_TARGETS_TO_BUILD=ARM`) without a `LLVM_DEFAULT_TARGET_TRIPLE`. 
```
bin/llc: error: unable to get target for '', see --version and --triple.
```
I think that is why tests in this directory have the `REQUIRES` along with a valid triple; either in command line (`-mtriple=aarch64`) or in the test file itself (`target triple = "aarch64--"`).
