The _Builtin_float interfaces were defined in $@rpath/lib/libswiftDarwin.dylib until macOS 10.14.4 and then in usr/lib/swift/libswiftDarwin.dylib after that. We were trying to use magic-symbols-for-install-name for the first one and @_originallyDefinedIn for the second one. However, @_originallyDefinedIn uses the @available introduced version as the first bound for $ld$previous$ which conflicts with the magic-symbols-for-install-name $ld$install_name$. Eventually @_originallyDefinedIn will need to support multiple install names, but until then just use it as-is and stop using magic-symbols-for-install-name. Add the missing @_originallyDefinedIn on FLT_RADIX, and match the watchOS/tvOS order between @_originallyDefinedIn and @available. There was no tvOS 7.0, the first one was 9.0. rdar://122351557
