[PATCH] D58236: Make address space conversions a bit stricter.

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

I think C probably requires us to allow this under an explicit cast, but we can at least warn about it.  It does not require us to allow this as an implicit conversion, and that should be an error.
