Don't lint when the item type is not a reference. `copied` only applies
to references.

4fcaab3d62 Split redundant_closure lint
Move the method checking into a new lint called
`redundant_closures_for_method_calls` and put it in the pedantic group.

This aspect of the lint seems more controversial than the rest.

67a9f20c91 Fix map_clone bad suggestion
`cloned` requires that the elements of the iterator must be references. This
change determines if that is the case by examining the type of the closure
argument and suggesting `.cloned` only if it is a reference. When the closure
argument is not a reference, it suggests removing the `map` call instead.

A minor problem with this change is that the new check sometimes overlaps
with the `clone_on_copy` lint.
