Backward\forward compatibility reasons any string shaped parameter in __builtin_cpu_supports should be accepted.
A given codebase might use a valid features that is supported in a new toolchain but not in the previous version.
```__builtin_cpu_supports("unsupported-features")```
It is valid to turn this into a constant false when the feature is not supported by the compiler.
