Is this "correct"? Should we not just return "" instead to simplify things and ensure that potentialType.Name isn't returned (in this case "X64")?

If this is the X64 nested type, we'll take the exit on line 86 and return an empty string. Nested types don't set a namespace so (potentialType.Namespace != "System.Runtime.Intrinsics.X86") is true.

GetHardwareIntrinsicIdshould not handle x64 intrinsics on x86.However, we were relying on this happening in
IsHardwareIntrinsic. So also fixingIsHardwareIntrinsicto work the same as CoreCLR VM.Cc @dotnet/ilc-contrib
