Cherry-pick [Swiftify] Don't import counted_by with suffixed integer literals (#82469) (#82594)
Integer literal expressions with types that are not of type `int` are printed with a suffix to indicate the type (e.g. `123U` or `456L` for `unsigned` and `long`). This is not valid syntax for integer literals in Swift, so until we fully translate the count expr syntax to Swift we need to avoid importing these count expressions. Also fixes some -Werror related stuff in test cases. rdar://154141719 (cherry picked from commit 374658a)
