__NSCFType has been using Int32 for _cfinfo. More recently in Swift 4, it’s been noticed that this can cause problems on 32-bit ARM and should be aligned with _CFInfo instead.

@shahmishal Looking at the CI logs @ https://ci.swift.org/job/swift-corelibs-foundation-PR-macOS/2/console for the macOS testing, I cant see it actually running the tests for Foundation, although it is building Foundation. Is this as expected? |

@spevans I'm curious about that too. |

Seems that this is ready to go, and already approved by @parkera |

Currently, there are no known issues on 32-bit ARM because of this. However, it'd be nice to fix this before some future change breaks because _cfinfo is an Int32.
